Export garbage collector thresholds for xfrm[4|6]_dst_ops Had a problem reported to me recently in which a high volume of ipsec connections on a system began reporting ENOBUFS for new connections eventually. It seemed that after about 2000 connections we started being unable to create more. A quick look revealed that the xfrm code used a dst_ops structure that limited the gc_thresh value to 1024, and always dropped route cache entries after 2x the gc_thresh. It seems the most direct solution is to export the gc_thresh values in the xfrm[4|6] dst_ops as sysctls, like the main routing table does, so that higher volumes of connections can be supported. This patch has been tested and allows the reporter to increase their ipsec connection volume successfully. Reported-by:

entry was tested for NULL near the beginning of the function, followed by a return, and there is no intervening modification of its value. A simplified version of the semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/ ) // <smpl> @r exists@ local idexpression x; expression E; position p1,p2; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\) ( *x == NULL | *x != NULL ) // </smpl> Signed-off-by:

Based on comments from Joe Perches <joe@perches.com>. Thanks. Fix IOFUNC_MEMIO macro. WriteFiFo##name##_MIO use the wrong struct name, this was missed because the macro was only called with this name. Clarify with _func that the defined types are functions. Add names to the parameters for better understanding the purpose. Signed-off-by:

The igb driver is currently initializing the mailbox function pointers after the phy. This causes issues as the phy init will return from the function early if there is no phy present. To resolve this I have moved the function pointer init to a location prior to the phy initialization so that serdes based adapters can also make use of SR-IOV. Signed-off-by:

This update cleans up the receive address register initialization. The main purpose of this is to clean out some redundancy that was introduced due to having multiple ways of setting the receive address registers. Instead of having a specialized function to set one register and one to set all of them it makes more sense to just go through the list calling the function that is needed to set the individual registers.
