Subject: [SCSI] cxgb3i: fix connection error when vlan is enabled
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a222ad1a4b2e3ca177a538482c99c519c1ce94d1;p=linux-beck.git

[SCSI] cxgb3i: fix connection error when vlan is enabled

There is a bug when VLAN is configured on the cxgb3 interface, the iscsi
conn. would be denied with message "cxgb3i: NOT going through cxgbi device."

This patch adds code to get the real egress net_device when vlan is configured.
