Description Allan Saddi 2001-01-07 23:40:02 UTC 
After upgrading the firmware of my Aironet cards to 4.13, I found
that the driver no longer worked. The console began to fill up with
these messages:

Jan  7 15:03:09 tranquility /kernel: an0: record length mismatch -- expected 134
, got 136

It seems that the new firmware returns an an_ltv_status structure which
is 2 bytes larger than expected. (What those 2 bytes are, I have no
idea!) Extending the structure by 2 bytes seems to quell the messages,
as well as make the driver work again.

I was not able to test these changes against cards with older firmware.

How-To-Repeat: 
Upgrade firmware to 4.13.

Hi,

This issue still exists. Your patch has been comitted to CURRENT,
but as you said there were two bytes, not one. I have now:

-       u_int16_t               an_spare[2];
+       u_int16_t               an_spare[5];

and now it works good. (Maybe four is enough, but with three, I still get
the same checksum missmatch.)
