net: fix network drivers ndo_start_xmit() return values
Fix up remaining drivers returning a magic or an errno value from their ndo_start_xmit() functions that were missed in the first pass: - isdn_net: missed conversion - bpqether: missed conversion: skb is freed, so return NETDEV_TX_OK - hp100: intention appears to be to resubmit skb once resources are available, but due to no queue handling it is dropped for now. - lapbether: skb is freed, so return NETDEV_TX_OK Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
