Subject: [PATCH net v2 00/12] Fixes for SONIC ethernet driver

Hi David,

Various SONIC driver problems have become apparent over the years,
including tx watchdog timeouts, lost packets and duplicated packets.

The problems are mostly caused by bugs in buffer handling, locking and
(re-)initialization code.

This patch series resolves these problems.

This series has been tested on National Semiconductor hardware (macsonic),
qemu-system-m68k (macsonic) and qemu-system-mips64el (jazzsonic).

The emulated dp8393x device used in QEMU also has bugs.
I have fixed the bugs that I know of in a series of patches at,
https://github.com/fthain/qemu/commits/sonic
---
Changed since v1:
 - Minor revisions as described in commit logs.
 - Deferred net-next patches.
