Subject: netdev-linux: Fix netdev_linux_send() return value in corner case.
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=c4c7a3d7a1c278548c92e5d317e4be4a8525f8c7;p=ovs.git

netdev-linux: Fix netdev_linux_send() return value in corner case.

A negative 'sock' means there was an error but netdev_linux_send() returns
a positive errno value on error.
