I have 2 laptops running hostap in Ad-Hoc mode. They ping each other
However to my surprise, the data length value in prism2_tx() and
prism2_rx() in hostap_hw.c are different!
In prism2_tx, right before the call to hfa384x_to_bap, I print skb->len
and find that it is 98. In prism2_rx, rxdesc.data_len is only 92. Does
anyone know what accounts for the 6 bytes difference in the receiver
A ping packet should appear at 98 bytes because:
Ethernet Hdr 14
IP Hdr 20
UDP Hdr 8
Ping Data 56
Total = 98 bytes
Why is rxdesc.data_len in prism2_rx only 92 then? Does anyone know how
to dump the payload of the packet for examination?
I am using:
Linksys WPC 11 v3
NICID: 0x801b v1.0.0
PRIID: 0x0015 v1.1.0
STAID: 0x001f v1.4.9
