What kind of switch is connected on the other end? It looks very similar. I've tested with dlink dgs-3620-28tc + Cisco SFP-H10GB-CU1M and (i'm not sure here) with loopback to 2nd port of Intel X520-DA2 card. I've found 2 problems in current ixgbe driver: 1) few seconds link loss on vlan reconfiguration (both create/destroy). 2) if you have configured vlans over ix0 and then run ifconfig ix0 vlanhwfilter your vlans will stop working until you "touch" ix0 vlan configuration (create one more vlan or destroy existing one). Patch solves both for me. -- Oleg. ================================================================ === Oleg Bulyzhin -- OBUL-RIPN -- OBUL-RIPE -- oleg@rinet.ru === ================================================================
