smsc75xx: fix smsc75xx_set_features()
If an attempt is made to disable RX checksums, USB adapter is changed but netdev->features is not, because smsc75xx_set_features() returns a non zero value. This throws errors from netdev_rx_csum_fault() : <devname>: hw csum failure Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S.
