Modified Files: src/sys/dev/pci: if_msk.c Log Message: add callout for re-filling RX ring - it's invoked when the RX refill code can't get enough buffers; fixes possible stall when the RXSTAT interrupt arrives while no buffers are available idea from OpenBSD if_msk.c rev. 1.131 as part of this remove the confusingly commented re-fill code from msk_jfree() and instead just invoke the callout if needed; also refill in msk_intr() only when running low instead of every RX intr; this simplifies the code, and gives small RX performance boost on my hardware (6%: ~38 MB/s -> ~40 MB/s) tested on SK-9E22 (Yukon-2 XL rev. A3) by me, and 88E8071 (Yukon-2 Extreme rev. B0) by Jogn Halfpenny; unfortunately still doesn't resolve the PR kern/53301 stall To generate a diff of this commit: cvs rdiff -u -r1.71 -r1.72 src/sys/dev/pci/if_msk.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
