What about ethtool_drvinfo? Or you mean drop all ethtool helpers? Regards, Roman

Some nice clean-ups that you should also consider for future changes: - reduce the duplication of tests/conditions in korina_send_packet(), a lot of them are testing for the same things and setting the same descriptor bits - move korina_tx() to a NAPI context instead of working from hard interrupt context - get rid of the MIPS dma_cache_* calls and instead properly use the DMA-API to allocate descriptors and invalidate/write-back skb->data > > Roman Yeryomin (7): > net: korina: don't use overflow and underflow interrupts > net: korina: optimize rx descriptor flags processing > net: korina: use NAPI_POLL_WEIGHT > net: korina: use GRO > net: korina: whitespace cleanup > net: korina: update authors > net: korina: bump version > > drivers/net/ethernet/korina.c | 230 > ++ > 1 file changed, 78 insertions(+), 152 deletions(-) > -- Florian
[PATCH net-next v2 0/7] korina: performance fixes and cleanup
Changes from v1: - use GRO instead of increasing ring size - use NAPI_POLL_WEIGHT instead of defining own NAPI_WEIGHT - optimize rx descriptor flags processing Roman Yeryomin (7): net: korina: don't use overflow and underflow interrupts net: korina: optimize rx descriptor flags processing net: korina: use NAPI_POLL_WEIGHT net: korina: use GRO net: korina: whitespace cleanup net: korina: update authors net: korina: bump version drivers/net/ethernet/korina.c | 230 ++ 1 file changed, 78 insertions(+), 152 deletions(-) -- 2.11.0
