- this also includes virtualization support on these devices Correct some vlan issues we were seeing in test, jumbo frames on vlans did not work correctly, this was all due to confused logic around HW filters, the new code should now work for all uses. Important fix: when mbuf resources are depeleted, it was possible to completely empty the RX ring, and then the RX engine would stall forever. This is fixed by a flag being set whenever the refresh code fails due to an mbuf shortage, also the local timer now makes sure that all queues get an interrupt when it runs, the interrupt code will then always call rxeof, and in that routine the first thing done is now to check the refresh flag and call refresh_mbufs. This has been verified to fix this type 'hang'. Similar code will follow in the other drivers. Finally, sync up shared code for the I350 support. Thanks to everyone that has been reporting issues, and helping in the debug/test process!!
