I try to catchup with some performance improvement that has been implemented then by Havard. The ring index logic and the TX error path modification are the biggest changes but some cleanup/debugging have been added along the way. The GEM revision will benefit from the Gigabit support. The series has been tested on several Atmel AT91 SoC with the two MACB/GEM flavors. v2: - modify the tx error handling: now uses a workqueue - information provided by ethtool -i were not accurate: removed Havard Skinnemoen (4): net/macb: memory barriers cleanup net/macb: change debugging messages net/macb: clean up ring buffer logic net/macb: Offset first RX buffer by two bytes Nicolas Ferre (4): net/macb: remove macb_get_drvinfo() net/macb: tx status is more than 8 bits now net/macb: ethtool interface: add register dump feature net/macb: better manage tx errors Patrice Vilchez (1): net/macb: Add support for Gigabit Ethernet mode drivers/net/ethernet/cadence/macb.c | 433 +++++++++++++++++++++++++----------- drivers/net/ethernet/cadence/macb.h | 30 ++- 2 files changed, 321 insertions(+), 142 deletions(-) -- 1.7.11.3
