[Linux-ATM-General] Solos driver weirdness in bridged mode

[Philip P. <phi...@re...>]

I'm seeing the following.  I have a Geos box running Openwrt from SVN (about 2 weeks old from trunk), and using the Geos platform target. I've configured RFC-2684 bridged mode for my Frontier Communications ADSL connection.

Openwrt shows me that:

br2684ctl -c 0 -e 0 -p 1 -a 0.0.35 -s 2040

is running as we'd expect.

However, I rebuilt the solos-pci driver to call:

list_vccs(0);

whenever it enters find_vcc(), which was always returning NULL will called with '35' as the argument.  I compiled the module with:

#define DEBUG 1
#define VERBOSE_DEBUG 1

It should be printing the entire table out whenever a packet is received...  But it doesn't... or it does but the table is empty.

So we're receiving 24 bytes of preamble (AA AA 03 ... 00 80), but we send either 16 bytes of MAC header with a 8 byte prefix in bridged mode (that's probably just the logging showing something before the header), or we send 8 bytes of prefix and 8 bytes of MAC header in routed mode.

My money is on routed mode.

Two things stand out from these traces...

(1) minor, we're seeing 8 bytes of prefix on transmit that we don't see on transmit (is that buffer descriptor or what?)... which incidentally is the same size as the pkt_hdr structure.
(2) we're consistently seeing find_vcc() return NULL

also not clear why "vpi" is usually a short in the code, but "vci" is more often an "int".

This is running 2.6.37...  I was previously using the same image with Qwest and PPPoA, and that seemed to work fine.

It's not clear to me why the hash of VC's is kept on a per-driver basis... shouldn't that go in atm common stuff?

Taking the 8-bytes of prefix and disassembling it as a struct pkt_hdr, I get:

9D 01 00 00 23 00 00 00

0x019d (413) == size
0x0000 (0)   == vpi
0x0023 (35)  == vci
0x0000 (0)   == type (PKT_DATA)

Oh, and another couple of nits, we say "Received: device 0", but "Transmitted: port 0"... and we dump the first 3 fields of the pkt_hdr on receive but not on transmit.

Thanks,
