When initializing igb driver (e.g. 82576, I350), IGB_FLAG_QUEUE_PAIRS is
set if adapter->rss_queues exceeds half of max_rss_queues in
igb_init_queue_configuration().
On the other hand, IGB_FLAG_QUEUE_PAIRS is not set even if the number of
queues exceeds half of max_combined in igb_set_channels() when changing
the number of queues by "ethtool -L".
In this case, if numvecs is larger than MAX_MSIX_ENTRIES (10), the size
of adapter->msix_entries[], an overflow can occur in
igb_set_interrupt_capability(), which in turn leads to an oops.
Fix this problem as follows:
- When changing the number of queues by "ethtool -L", set
IGB_FLAG_QUEUE_PAIRS in the same way as initializing igb driver.
- When increasing the size of q_vector, reallocate it appropriately.
(With IGB_FLAG_QUEUE_PAIRS set, the size of q_vector gets larger.)
Another possible way to fix this problem is to cap the queues at its
initial number, which is the number of the initial online cpus. But this
is not the optimal way because we cannot increase queues when another
cpu becomes online.
Note that before commit cd14ef54d25b ("igb: Change to use statically
allocated array for MSIx entries"), this problem did not cause oops
but just made the number of queues become 1 because of entering msi_only
mode in igb_set_interrupt_capability().

net: Convert drivers to IFF_NO_QUEUE and cleanup afterwards
This series converts in-tree users away from the old and deprecated
'tx_queue_len = 0' idiom, adds a warning to notify out-of-tree driver
maintainers that there is need for action on their behalf and finally drops any
workarounds in scheduling algorithm implementations.

Those were all workarounds for the formerly double meaning of
tx_queue_len, which broke scheduling algorithms if untreated.
Now that all in-tree drivers have been converted away from setting
tx_queue_len = 0, it should be safe to drop these workarounds for
categorically broken setups.

Due to the introduction of IFF_NO_QUEUE, there is a better way for
drivers to indicate that no qdisc should be attached by default. Though,
the old convention can't be dropped since ignoring that setting would
break drivers still using it. Instead, add a warning so out-of-tree
driver maintainers get a chance to adjust their code before we finally
get rid of any special handling of tx_queue_len == 0.

When we enter D0i3, we must stop TXing otherwise the
sequence number we use might conflict with the firmware's
internal TX. In order to do so, we have
IWL_MVM_STATUS_IN_D0I3 which should prevent any Tx while we
enter D0i3. There is a bug in this code since we may Tx even
if IWL_MVM_STATUS_IN_D0I3 is set. This can happen as long as
mvm->d0i3_ap_sta_id is not set.
To make sure that we don't have any packet in the Tx path
while we set mvm->d0i3_ap_sta_id, call synchronize_net only
after we already set mvm->d0i3_ap_sta_id.

Currently if we wake up during D0I3 due to beacon loss we disconnect
immediately. This behaviour causes redundant disconnection, which could
be prevented by polling as it is usually done in mac80211.
Instead, we prefer reporting beacon loss and let mac80211 try polling
before disconnection.

This lead to out-of-bound accesses and invalid values for

I remove duplicated routines which related rtl92cu_set_hw_reg().
1. rtl92c_set_qos() and HW_VAR_AC_PARAM routine are similar code.
so i replace code with rtlpriv->cfg->ops->set_hw_reg().
2. rtl92c_set_mac_addr() and 'HW_VAR_ETHER_ADDR' case at
rtl92cu_set_hw_reg() routine are similar code.
so i removed rtl92c_set_mac_addr() function.
also it was not used anywhere.
3. remove HW_VAR_ACM_CTRL routine in rtl92cu_set_hw_reg().
if rtl_usb->acm_method is not EACMWAY2_SW, HW_VAR_ACM_CTRL is called
from HW_VAR_AC_PARAM. but it never called. because acm_method is always
EACMWAY2_SW. so i remove acm_method check routine
and HW_VAR_ACM_CTRL routine.
both usb and pci interface is not used HW_VAR_ACM_CTRL.
but i can't test pci interface module, so i didn't modify pci code.

rtl92c_set_xxx_filter is same routine with rtl92cu_set_hw_reg.
so i remove those functions that are rtl92c_set_xxx_filter.
(rtl92c_get_xxx_filter is also same reason.)
also i add code updating struct rtl_mac member variable in the

after that, no more _update_mac_setting is not useful. thus i remove that.

====================
net: Identifier Locator Addressing - Part I
This patch set provides rudimentary support for Identifier Locator
Addressing or ILA. The basic concept of ILA is that we split an IPv6
address into a 64 bit locator and 64 bit identifier. The identifier is
the identity of an entity in communication ("who"), and the locator
expresses the location of the entity ("where"). Applications
use externally visible address that contains the identifier.
When a packet is actually sent, a translation is done that
overwrites the first 64 bits of the address with a locator.
The packet can then be forwarded over the network to the host where
the addressed entity is located. At the receiver, the reverse
translation is done so the that the application sees the original,
untranslated address. Presumably an external control plane will
provide identifier->locator mappings.
v2:
- Fix compilation erros when LWT not configured
- Consolidate ILA into a single ila.c
v3:
- Change pseudohdr argument od inet_proto_csum_replace functions to
be a bool
v4:
- In ila_build_state check locator being in netlink params before
allocating tunnel state
The data path for ILA is a simple NAT translation that only operates
on the upper 64 bits of a destination address in IPv6 packets. The
basic process is:
1) Lookup 64 bit identifier (lower 64 bits of destination)
2) If a match is found
a) Overwrite locator (upper 64 bits of destination) with
the new locator
b) Adjust any checksum that has destination address included in
pseudo header
3) Send or receive packet
ILA is a means to implement tunnels or network virtualization without
encapsulation. Since there is no encapsulation involved, we assume that
stateless support in the network for IPv6 (e.g. RSS, ECMP, TSO, etc.)
just works. Also, since we're minimally changing the packet many of
the worries about encapsulation (MTU, checksum, fragmentation) are
not relevant. The downside is that, ILA is not extensible like other
encapsulations (GUE for instance) so it might not be appropriate for
all use cases. Also, this only makes sense to do in IPv6!
A key aspect of ILA is performance. The intent is that ILA would be
used in data centers in virtualizing tasks or jobs. In the fullest
incarnation all intra data center communications might be targeted to
virtual ILA addresses. This is basically adding a new virtualization
capability to the existing services in a datacenter, so there is a
strong expectation is that this does not degrade performance for
existing applications.
Performance seems to be dependent on how ILA is hooked into kernel.
ILA can be implemented under some different models:
- Mechanically it is a form a stateless DNAT
- It can be thought of as a type of (source) routing
- As a functional replacement of encapsulation
In this patch set we hook into the data path using Light Weight
Tunnels (LWT) infrastructure. As part of that, we add support in LWT
to redirect dst input. iproute will be modified to take a new ila encap
type. ILA can be configured like:
ip route add 3333:0:0:1:5555:0:2:0/128 \
encap ila 2001:0:0:2 via 2401:db00:20:911a:face:0:27:0
ip -6 addr add 3333:0:0:1:5555:0:1:0/128 dev eth0
ip route add table local local 2001:0:0:1:5555:0:1:0/128
encap ila 3333:0:0:1 dev lo
So sending to destination 3333:0:0:1:5555:0:2:0 will have destination
of 2001:0:0:2:5555:0:2:0 on the wire.
Performance results are below. With ILA we see about a 10% drop in
pps compared to non-ILA. Much of this drop can be attributed to the
loss of early demux on input (translation occurs after it is attempted).
We will address this in the next patch set. Also, IPvlan input path
does not work with ILA since the routing is bypassed-- this will
be addressed in a future patch.
Performance testing:
Performing netperf TCP_RR with 200 clients:
Non-ILA baseline
84.92% CPU utilization
1861922.9 tps
93/163/330 50/90/99% latencies
ILA single destination
83.16% CPU utilization
1679683.4 tps
105/180/332 50/90/99% latencies

Adding new module name ila. This implements ILA translation. Light
weight tunnel redirection is used to perform the translation in
the data path. This is configured by the "ip -6 route" command
using the "encap ila <locator>" option, where <locator> is the
value to set in destination locator of the packet. e.g.
ip -6 route add 3333:0:0:1:5555:0:1:0/128 \
encap ila 2001:0:0:1 via 2401:db00:20:911a:face:0:25:0
Sets a route where 3333:0:0:1 will be overwritten by
2001:0:0:1 on output.
