Subject: netdev-linux: Fix netdev_linux_send() return value in corner case.
X-Git-Tag: v1.9.3~39
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;ds=sidebyside;h=3f079d423336ed82929fcaf85a4475c88d5f3f6e;p=cascardo%2Fovs.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.
