>Description:
Incorrect media (1000baseSX instead of 1000baseT) shown in ifconfig with INTEL
X520-T2 10G Dual-port Ethernet Server Adapter, RJ45/2 when connecting to the
gigabit switch with copper ports:
ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO>
ether 00:1e:67:07:80:d8
media: Ethernet autoselect (1000baseSX <full-duplex>)
status: active
ix1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO>
ether 00:1e:67:07:80:d8
media: Ethernet autoselect (1000baseSX <full-duplex>)
status: active
Current network adapter doesn't have optic ports or modules, only build-in
copper ports. That's why can't gather this interfaces with other gigabit in
lagg with lacp (but this is another problem fixed in PR: 176097).
>How-To-Repeat:
Simply ifconfig ixX up, where X is the number of interface.
>Fix:
Quick and dirty hack is to replace the IFM_1000_SX with IFM_1000_T in ixgbe.c:
