Hi Sam, > 3. If you want to use ath cards in the minipci slots you'll need to use > a newer hal than what is in CVS. I believe the tarball at > http://www.freebsd.org/~sam/ath_hal-20060909.tgz will work but am not > sure. I'm working on getting a known-good version together. I have done this, but it looks like packets (ipv6 and ipv4) are shifted 2 bytes: Here are part of a tcpdump on a wrap (non-arm) board showing packets coming from the arm board: tcpdump -p -i ath0 -n -s 0 -e -X ether src 00:02:6f:34:21:a2 ... 14:41:01.012648 00:02:6f:34:21:a2 > 33:33:00:00:00:01, ethertype IPv6 (0x86dd), length 96: 1101:fd9c:6829:597c:10:202:6fff:fe34 > 21a2:ff0e::: [|HBH] 0x0000: 0000 6000 0000 0028 1101 fd9c 6829 597c ..`....(....h)Y| 0x0010: 0010 0202 6fff fe34 21a2 ff0e 0000 0000 ....o..4!....... 0x0020: 0000 0000 0000 0000 0001 02ba 02ba 0028 ...............( 0x0030: cefe 0020 4705 c948 001c fd9c 6829 597c ....G..H....h)Y| 0x0040: 0010 0202 6fff fe34 21a2 0100 7338 0000 ....o..4!...s8.. 0x0050: 0503 .. 14:41:01.162480 00:02:6f:34:21:a2 > ff:ff:ff:ff:ff:ff, ethertype IPv4 (0x0800), length 100: IP0 truncated-ip - 17578 bytes missing! 81.110.10.10 > 10.2.10.10: ip 0x0000: 0800 4500 0054 0027 0000 4001 516e 0a0a ..E..T.'..@.Qn.. 0x0010: 0a02 0a0a 0aff 0800 52b4 0203 0026 456c ........R....&El 0x0020: 2e95 0006 4418 0809 0a0b 0c0d 0e0f 1011 ....D........... 0x0030: 1213 1415 1617 1819 1a1b 1c1d 1e1f 2021 ...............! 0x0040: 2223 2425 2627 2829 2a2b 2c2d 2e2f 3031 "#$%&'()*+,-./01 0x0050: 3233 3435 3637 234567 The first packet is fd9c:6829:597c:10:202:6fff:fe34:21a2 multicasting to ff0e::1 and the second packet is 10.10.10.2 broadcasting to 10.10.10.255. Doing a tcpdump on the arm itself, packets going out seems to be ok, but packets that it receives is shifted 2 bytes in the other direction. The low-level stuff inside the ath driver seems to work though. The cards are in adhoc mode and pick the other up according to "ifconfig ath0 list sta".
