[PATCH net-next] igbvf: do not force carrier off in igbvf_msix_other()

[Stefan Assmann <sassmann@kpanic.de>]

Currently carrier is forced off in igbvf_msix_other(). This seems
unnecessary and causes multiple calls to igbvf_watchdog_task(), resulting
in multiple link up messages when calling dhclient for example.
[  111.818106] igbvf 0000:00:04.0: Link is Up 1000 Mbps Full Duplex
[  111.819347] IPv6: ADDRCONF(NETDEV_UP): eth5: link is not ready
[  111.820509] IPv6: ADDRCONF(NETDEV_CHANGE): eth5: link becomes ready
[  111.822983] igbvf 0000:00:04.0: Link is Up 1000 Mbps Full Duplex
[  115.152421] igbvf 0000:00:04.0: Link is Up 1000 Mbps Full Duplex
compared to
[ 1040.422161] igbvf 0000:00:04.0: Link is Up 1000 Mbps Full Duplex
[ 1040.423447] IPv6: ADDRCONF(NETDEV_UP): eth5: link is not ready
[ 1040.424622] IPv6: ADDRCONF(NETDEV_CHANGE): eth5: link becomes ready
when this patch is applied.
