Packets with crc error can be captured using corresponding flag of iw. iw phy phy0 interface add wlan0 type monitor flags fcsfail However, there is also option for plcpfail flag but I never obtained any packet with plcpfail using this flag. Any info about that will be helpful.

There is a comment in ath9k/common.c which says that a bad checksum is ignored in monitor mode, but I have so far never been able to receive a packet with bad FCS (I do not know how to generate such packets, so I might just be too lucky that all packets are received unimpaired). Does ath9k hardware drop packets with bad FCS directly? If so, can it be disabled?
