Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2017-04-20 This series contains updates to e1000, e1000e, igb/vf and ixgb. Tobias Klauser cleans up e1000, ixgb and igbvf from having a local function or structure for netdev stats. Bernd Faust fixes an issue for 82579 devices, where the clock frequency was being incorrectly set for these devices. These devices only support 96MHz, so make sure they are set to use only that. Yury Kylulin extends the work Jake and Alex did for ixgbe in MAC filter handling into the igb driver. Kim Tatt Chuah enables igb to wake up by packet and to read the necessary Wake Up Status (WUS) and Wake Up Packet Memory (WUPM) registers. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
