src/sys/dev/pci/ixgbe [netbsd-8]: ix_txrx.c ixgbe.c ixgbe.h
ixgbe_type.h ixv.c
Log Message:
Pull up the following, requested by msaitoh in ticket #1933:
sys/dev/pci/ixgbe/ix_txrx.c 1.105-1.116 via patch
sys/dev/pci/ixgbe/ixgbe.c 1.345-1.346,1.349 via
patch
sys/dev/pci/ixgbe/ixgbe.h 1.94-1.98
sys/dev/pci/ixgbe/ixgbe_type.h 1.62
sys/dev/pci/ixgbe/ixv.c 1.193,1.195-1.196
- Clear the WTHRESH bit field before writing it.
- Optimize ixgbe_txeof().
- Use kmem_zalloc() instead of malloc(,M_ZERO).
- Add QPRDC(Queue Packet Receive Drop Count) into iqdrops.
- No functional change
- Move assignment of TXD.
- ixv(4): Remove unused IFF_OACTIVE.
- Don't include the Flow Director related members to reduce the
size of struct tx_ring. On amd64 and aarch64, the real size is
not changed because of the alignment.
- The descriptor ring size and the alignment are tested in the
attach function, so it's not required to use
roundup2(size, DBA_ALIGN).
- Use #ifdef LRO more to reduce the size of struct rx_ring.
- Change "me" from 32bit to 8bit because the max is 128.
This commit doesn't change the real size of ix_queue, tx_ring
and rx_ring because of the alignment.
- Th RSC (hardware receive side coalescing) feature has been
disabled all along, so enclose the code with #ifdef RSC.
- Remove unused.
- Modify for the readability.
- Modify comment.
- Fix comment. Whitespace.
