The "rx errors" value is generated by summing 4 error counters from the card internal stats structure in airo_read_stats() : RxOverrun, RxPlcpFormatErr, RxPlcpLengthErr and RxMacCrcErr.
Altough my connection is up and running, I also observe a high rate of RxMacCrcErr errors :
% grep MacCrc /proc/driver/aironet/eth1/Stats RxMacCrcErr: 7688 RxMacCrcOk: 11399
I think that these errors are probably just related to the quality of the radio link, and do not reflect something bad, that would occur in the driver itself.
