This patch adds a new network portal attribute for iser, that lives
under existing iscsi-target configfs layout at:
/sys/kernel/config/target/iscsi/$TARGETNAME/$TPGT/np/$PORTAL/iser
When lio_target_np_store_iser() is enabled, iscsit_tpg_add_network_portal()
will attempt to start an rdma_cma network portal for iser-target, only if
the external ib_isert module transport has been loaded.
When disabled, iscsit_tpg_del_network_portal() will cease iser login service
on the network portal, and release any external ib_isert module reference.
v4 changes:
- Add request_module for ib_isert to lio_target_np_store_iser()

OVS locking was recently changed to have private OVS lock which
simplified overall locking. Therefore there is no need to have
another global genl lock to protect OVS data structures. Following
patch uses of parallel_ops genl family for OVS. This also allows
more granual OVS locking using ovs_mutex for protecting OVS data
structures, which gives more concurrencey. E.g multiple genl
operations OVS_PACKET_CMD_EXECUTE can run in parallel, etc.

All genl callbacks are serialized by genl-mutex. This can become
bottleneck in multi threaded case.
Following patch adds an parameter to genl_family so that a
particular family can get concurrent netlink callback without
genl_lock held.
New rw-sem is used to protect genl callback from genl family unregister.
in case of parallel_ops genl-family read-lock is taken for callbacks and
write lock is taken for register or unregistration for any family.
In case of locked genl family semaphore and gel-mutex is locked for
any openration.

Currently, packet_sock has a struct tpacket_stats stats member for
TPACKET_V1 and TPACKET_V2 statistic accounting, and with TPACKET_V3
``union tpacket_stats_u stats_u'' was introduced, where however only
statistics for TPACKET_V3 are held, and when copied to user space,
TPACKET_V3 does some hackery and access also tpacket_stats' stats,
although everything could have been done within the union itself.
Unify accounting within the tpacket_stats_u union so that we can
remove 8 bytes from packet_sock that are there unnecessary. Note that
even if we switch to TPACKET_V3 and would use non mmap(2)ed option,
this still works due to the union with same types + offsets, that are
exposed to the user space.

There's a 4 byte hole in packet_ring_buffer structure before
prb_bdqc, that can be filled with 'pending' member, thus we can
reduce the overall structure size from 224 bytes to 216 bytes.
This also has the side-effect, that in struct packet_sock 2*4 byte
holes after the embedded packet_ring_buffer members are removed,
and overall, packet_sock can be reduced by 1 cacheline:
Before: size: 1344, cachelines: 21, members: 24
After: size: 1280, cachelines: 20, members: 24

====================
This is a joint effort with Willem to bring optional i) tx hw/sw
timestamping into PF_PACKET, that was reported by Paul Chavent,
and ii) to expose the type of timestamp to the user, which is in
the current situation not possible to distinguish with the RX_RING
and TX_RING API (but distinguishable through the normal timestamping
API), reported by Richard Cochran. This set is based on top of
``packet: account statistics only in tpacket_stats_u''. Related

Currently, there is no way to find out which timestamp is reported in
tpacket{,2,3}_hdr's tp_sec, tp_{n,u}sec members. It can be one of
SOF_TIMESTAMPING_SYS_HARDWARE, SOF_TIMESTAMPING_RAW_HARDWARE,
SOF_TIMESTAMPING_SOFTWARE, or a fallback variant late call from the
PF_PACKET code in software.
Therefore, report in the tp_status member of the ring buffer which
timestamp has been reported for RX and TX path. This should not break
anything for the following reasons: i) in RX ring path, the user needs
to test for tp_status & TP_STATUS_USER, and later for other flags as
well such as TP_STATUS_VLAN_VALID et al, so adding other flags will
do no harm; ii) in TX ring path, time stamps with PACKET_TIMESTAMP
socketoption are not available resp. had no effect except that the
application setting this is buggy. Next to TP_STATUS_AVAILABLE, the
user also should check for other flags such as TP_STATUS_WRONG_FORMAT
to reclaim frames to the application. Thus, in case TX ts are turned
off (default case), nothing happens to the application logic, and in
case we want to use this new feature, we now can also check which of
the ts source is reported in the status field as provided in the docs.

Jeff Kirsher says:
====================
This series contains updates to ixgbe, igb and pci.
The ixgbe changes contains a fix to a possible divide by zero by bailing
out of the ixgbe_update_itr() function if the last interrupt timeslice is
zero. In addition, support is added for the new OCP x520 adapter as well
as LX support for 82599 devices. Jacob provides a patch to change
variable wol_supported to wol_enabled to better reflect what the code
is actually doing (i.e. checking if WoL is enabled).
Alex adds SRIOV helper function to pci that will determine if a PF
has any VFs that are currently assigned to a guest.
The remaining 8 patches are against igb and contain the following changes:
* implement SERDES loopback configuration for i210 devices by unsetting
sigdetect bit, so as to fix Ethtool loopback test failure
* add support for the SMBI semaphore for I210/I211 devices
* implement the new generic pci_vfs_assigned helper function (Alex's PCI
helper function)
* display warning when link speed is downgraded due to Smartspeed
* ensure that VLAN hardware filtering remains enabled when the device is
in promiscuous mode and VT mode simultaneously
* cleanup dead code in igb
* bump the driver version
v2: updated the PCI patch to add SRIOV helper function to remove extern
from the declaration of pci_vfs_assigned in pci.h and return 0 if
SR-IOV is disabled which is inline with other PCI SR-IOV functions

This patch implements SERDES loopback configuration for i210 devices by
unsetting sigdetect bit, so as to fix Ethtool loopback test failure. Old
sigdetect code is also simplified to take care of all devices newer than 82580

This patch adds LX support to 82599 devices. This is an alternate patch to
the one suggested by Stefan Behte <s.behte@babiel.com>
In addition this patch includes some cleanups such as:
- removed parenthesis around "x == y ||" lines inside an if statement for
consistency.
- grouped the sx/lx sfp types along with srlr in ixgbe_get_settings() since
they all have the same supported, advertised and port values.

The variable wol_supported really is just checking whether it is enabled, rather
than whether it is supported. If it is enabled it will be supported, but this
does not necessarily hold true the other way around. This patch renames the
variable to avoid confusion.
