Subject: [PATCH] sky2: incorrect length on receive packets
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=489b10c1f63fafcb89c330a0603694652068132a;p=deliverable%2Flinux.git

[PATCH] sky2: incorrect length on receive packets

The previous change to do fragmented receive (post 2.6.18) introduced a bug
where packets are passed up with size set to the size of the receive buffer
not the actual received data.  IP silently trims this so it didn't show up
right away.
