I'm not adding support. I am sending a patch removing support for cards
that do not work with the current driver and have not worked since 2.6.31.
I have already been though this process once in the beginning of
November 2009, and gave a detailed bug report. Perhaps things got
lost in the handoff between netxen to qlogic. The fact of the matter
is I reported this before 2.6.32 came out, and the card still does not
work. In that process I tried a newer firmware rev that does not even
work on 2.6.31.
If you want to jump on this and find a solution that works on the 0x41
hardware rev that would be great. Otherwise it is time for me to cut
my losses, and be a good community citizen by documenting the driver
does not work on the hardware I have.
The failure mode is that the driver reports a firmware hang, and
I don't get link. At which point the card is totally useless.
