net: fix network driver ndo_start_xmit() return values (part 1)
Fix up drivers that return an errno value to qdisc_restart(), causing qdisc_restart() to print a warning and requeue/retransmit the skb. - xpnet: memory allocation error, intention is to drop - ethoc: oversized packet, packet must be dropped - ibmlana: skb freed: use after free - rrunner: skb freed: use after free Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
