Subject: FYI:  msdu-desc must be multiple of 8.
Date: Tue, 13 May 2014 15:34:21 -0700	[thread overview]
Message-ID: <53729DED.6000104@candelatech.com> (raw)

I just hit strange and wonderful crashes because I managed to use
an msdu-desc length that was not an even multiple of 8.  Firmware
has assumption (bug, really) about this.

Bug is only triggerable if you fill up tx-descs, so have to flood UDP
to hit easily.  I was trying 812 buffers, but 808 works just fine.
(non CT firmware will not let you do less that 1024, no matter what you
request, btw).

Easy to fix though once you know the problem.

Thanks,
Ben
