I'm sorry, I don't understand you.
I guess you refer to this fragment:
GEN8> grep -C3 decry /usr/src/sys/dev/bwn/if_bwn.c
if (macstat & BWN_RX_MAC_DEC && rx_mac_dec_rpt++ < 50)
device_printf(sc->sc_dev,
"RX decryption attempted (old %d keyidx %#x)\n",
BWN_ISOLDFMT(mac),
(macstat & BWN_RX_MAC_KEYIDX) >> BWN_RX_MAC_KEYIDX_SHIFT);
GEN8>
but I can't see MAC_DECERR here.
Anyway, are you saying there is some error occuring,
or are you saying it's a false positive?
Many thanks
