Analyze and fix the following issue in the Linux kernel code: ixgbe: fix bug with vlan strip in promsic mode
Problem Details: The ixgbe driver was setting up 82598 hardware correctly, so that when promiscuous mode was enabled hardware stripping was turned off. But on 82599 the logic to disable/enable hardware stripping is different, and the code was not updated correctly when the hardware vlan stripping was enabled as defaul...
