Couple of things.
first i am using cisco aironet pcmcia 350 series card, with a 5.41
firmware. first i had issues with the changed sizes of the config rids,
so i added additional padding as the debug message indicated.

next, the packet length is indicated to be 2 bytes more than it
actually is. So, i get debug messages but if the mtu is 1500 and the card
get 1500 bytes during an ftp transfer, the length as seen in
line 1320 of src/sys/dev/ic/an.c is 2 more than what should be the
i tried the following to verify that this intuition was correct.
- m->m_pkthdr.len = m->m_len = sizeof(struct ieee80211_frame) + len;
+ m->m_pkthdr.len = m->m_len = sizeof(struct ieee80211_frame) + len - 2;
and it all works fine. i know that this is not a fix but i am
unable to nail it correctly. Can someone kindly help me ?
