2018-01-26i40e: fix FW_LLDP flag on initAlan Brady
Using ethtool --set-priv-flags disable-fw-lldp <on/off> is persistent across reboots/reloads so we need some mechanism in the driver to detect if it's on or off on init so we can set the ethtool private flag appropriately. Without this, every time the driver is reloaded the flag will default to off regardless of whether it's on or off in FW. We detect this by first attempting to program DCB and if AQ fails returning I40E_AQ_RC_EPERM, we know that LLDP is disabled in FW.

2018-01-26i40e: Implement an ethtool private flag to stop LLDP in FWDave Ertman
Implement the private flag disable-fw-lldp for ethtool to disable the processing of LLDP packets by the FW. This will stop the FW from consuming LLDPDU and cause them to be sent up the stack. The FW is also being configured to apply a default DCB configuration on link up. Toggling the value of this flag will also cause a PF reset. Disabling FW DCB will also disable DCBx.

2018-01-26i40evf: Allow turning off offloads when the VF has VLAN setPaweł Jabłoński
This patch adds back the capability to turn off offloads when VF has VLAN set. The commit 0a3b4f702fb1 ("i40evf: enable support for VF VLAN tag stripping control") adds the i40evf_set_features function and changes the 'turn off' flow for offloads.

2018-01-26i40e: Fix for adding multiple ethtool filters on the same locationPatryk Małek
This patch reorders i40e_add_del_fdir and i40e_update_ethtool_fdir_entry calls so that we first remove an already existing filter (inside i40e_update_ethtool_fdir_entry using i40e_add_del_fdir) and then we add a new one with i40e_add_del_fdir. After applying this patch, creating multiple identical filters (with the same location) one after another doesn't revert their behavior but behaves correctly.

2018-01-26ixgbevf: don't bother clearing tx_buffer_info in ixgbevf_clean_tx_ring()Emil Tantilov
In the case of the Tx rings we need to only clear the Tx buffer_info when we are resetting the rings. Ideally we do this when we configure the ring to bring it back up instead of when we are taking it down in order to avoid dirtying pages we don't need to. In addition we don't need to clear the Tx descriptor ring since we will fully repopulate it when we begin transmitting frames and next_to_watch can be cleared to prevent the ring from being cleaned beyond that point instead of needing to touch anything in the Tx descriptor ring. Finally with these changes we can avoid having to reset the skb member of the Tx buffer_info structure in the cleanup path since the skb will always be associated with the first buffer which has next_to_watch set.

Pull networking fixes from David Miller: 1) The per-network-namespace loopback device, and thus its namespace, can have its teardown deferred for a long time if a kernel created TCP socket closes and the namespace is exiting meanwhile. The kernel keeps trying to finish the close sequence until it times out (which takes quite some time). Fix this by forcing the socket closed in this situation, from Dan Streetman. 2) Fix regression where we're trying to invoke the update_pmtu method on route types (in this case metadata tunnel routes) that don't implement the dst_ops method. Fix from Nicolas Dichtel. 3) Fix long standing memory corruption issues in r8169 driver by performing the chip statistics DMA programming more correctly. From Francois Romieu. 4) Handle local broadcast sends over VRF routes properly, from David Ahern. 5) Don't refire the DCCP CCID2 timer endlessly, otherwise the socket can never be released. From Alexey Kodanev. 6) Set poll flags properly in VSOCK protocol layer, from Stefan Hajnoczi. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: VSOCK: set POLLOUT | POLLWRNORM for TCP_CLOSING dccp: don't restart ccid2_hc_tx_rto_expire() if sk in closed state net: vrf: Add support for sends to local broadcast address r8169: fix memory corruption on retrieval of hardware statistics. net: don't call update_pmtu unconditionally net: tcp: close sock if net namespace is exiting

select(2) with wfds but no rfds must return when the socket is shut down by the peer. This way userspace notices socket activity and gets -EPIPE from the next write(2). Currently select(2) does not return for virtio-vsock when a SEND+RCV shutdown packet is received.

Based on: commit 7ec0116c9131 ("igb: Use length to determine if descriptor is done") This change makes it so that we use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed.

onlink verification needs to do a lookup in potentially different table than the table in fib6_config and without the RT6_LOOKUP_F_IFACE flag. Change ip6_nh_lookup_table to take table id and flags as input arguments. Both verifications want to ignore link state, so add that flag can stay in the lookup helper.

Document "renesas,can-r8a7743" and "renesas,can-r8a7745" compatible strings. Since the fallback compatible string ("renesas,rcar-gen2-can") activates the right code in the driver, no driver change is needed.
