We would get an oops on RX on -ENOMEM by passing NULL to the hardware on ath_rx_buf_link(). The oops would look something like this: ath_rx_tasklet+0x515/0x53b ath9k_tasklet+0x48 tasklet_action __do_softirq irq_exit do_IRQ RIP: ath_rx_buf_link+0x3a We correct this by handling the requeue directly on the ath_rx_tasklet() and trying to allocate an skb *prior* to sending up the last hardware processed skb. If we run out of memory this gauranteees we have skbs to work with while it simply drops new received frames. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.
