Hello,

This fix did not yet make it in to the tg3 driver as of -rc1. This patch
fixes an occasional crash problem with several of our boxes and the tg3
driver (fix from Jes).

Hi Dave

Here's another one, tg3_recycle_rx() needs to declare dest_idx_unmasked as unsigned int or it will do funny stuff on modular division once we go above 31 bit values.

I don't think this is the bug that Scott was hitting, but it is of course possible. It takes about 120 minutes for me with a packet generator, spewing out 64 byte packets, to trigger it.

Cheers, Jes
