Bug description:
So I finally got around to testing the wl driver on some Dell hardware I had.
It took me awhile to notice a huge bug, and to actually place the blame on the
wl driver, since it was so obscure.
My configuration is a Linksys WRT54G AP, setup to NAT my local network to the
internet (T1). I put the bcm4321 card in my laptop.
Applications such as Firefox, Pidgin and Evolution were working fine. SSH
connections to machines on my local LAN were also working fine.
However, I then tried to SSH to machines outside the LAN, and the connections
froze. Using -vv on ssh, it actually made the connection, but then stopped
shortly after authentication.
Trying to debug the issue, I used telnet to connect to the external ports. A
SYN packet was sent, but never got an ACK. It wouldn't even connect to port 80
on web servers that Firefox was connecting to with no problems.
So the issue is not one of protocol or port, but one of how ssh and telnet's
TCP-IP is setup, and how the NAT is handled. A direct connection to the
internet (Not NAT'd) works fine.
I confirmed this with another person who was also using wl, and he was able to
reproduce it with a different AP (still NAT) on both of our 2.6.24 and 2.6.26
kernels (hardy and intrepid).
So this isn't a regression either. I would spend more time on this, but I
suspect I wouldn't be able to get further than "yeah, it's broken".
