net: fix network drivers ndo_start_xmit() return values (part 3)
net: fix network drivers ndo_start_xmit() return values (part 3) Fix up wireless drivers that return an errno value to qdisc_restart(), causing qdisc_restart() to print a warning an requeue/retransmit the skb. - airo: transmission not implemented for chip, intention is to free and abort - ipw2200: transmission not implemented for promiscous mode, intention is to drop - prism54: intention is to drop - wl3501_cs: intention appears to be to drop - zd1201: error counter indicates intention is to drop All drivers compile tested.
