This is a resubmit backport of commit 92c6b8d16a
to kernel version 2.6.32. The gentoo bug report can be found at
https://bugs.gentoo.org/show_bug.cgi?id=301091. Thanks to Matt Carlson for his
assistance and working me to fix a regression caused by the initial patch. The
original description is as follows:
The 5906 has trouble with fragments that are less than 8 bytes in size. This
patch works around the problem by pivoting the 5906's transmit routine to
tg3_start_xmit_dma_bug() and introducing a new SHORT_DMA_BUG flag that enables
code to detect and react to the problematic condition.
