A while ago I submitted this patch for NAPI support for SB1250 / SB1480. I have tested it again on the recent (6/3/06) linux-mips kernel. Tom Below is the original posting. This patch adds NAPI support for the Broadcom Sibyte SB1xxx family. The changes are limited to adding a new config key SBMAC_NAPI to the drivers/ net/Kconfig and by adding the poll op and interrupt support to drivers/ net/sb1250-mac.c. This patch also has a fix to drivers/net/sb1250-mac.c, the dma descriptor table ptr is allocated, aligned and the aligned ptr is freed. If the ptr was not already aligned (usually is) then the free would not work of what was returned by the kmalloc. A variable was added to store the unaligned pointer so that it could be properly freed. I have tested this patch on a BCM91250A-SWARM Pass 2 / An. Mark Mason from Broadcom was very helpful and tested this patch on at least a 1480. TomOn Thu, 25 May 2006 08:35:05 -0500, Martin Michlmayr <tbm@xxxxxxxxxx> wrote:

Is there a particular maintainer(s) that I should cc on this patch?jgarzik@xxxxxxxxx He just reminded people that the merge window for 2.6.18 will open soon (and that he's collecting patches for that already) so now would be an excellent time. Thanks.
