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. Changed since v2: - Minor revisions as described in commit logs.
Finn Thain (12): net/sonic: Add mutual exclusion for accessing shared state net/sonic: Clear interrupt flags immediately net/sonic: Use MMIO accessors net/sonic: Fix interface error stats collection net/sonic: Fix receive buffer handling net/sonic: Avoid needless receive descriptor EOL flag updates net/sonic: Improve receive descriptor status flag check net/sonic: Fix receive buffer replenishment net/sonic: Quiesce SONIC before re-initializing descriptor memory net/sonic: Fix command register usage net/sonic: Fix CAM initialization net/sonic: Prevent tx watchdog timeout
