The patch titled forcdeth: increase max_interrupt_work has been removed from the -mm tree. Its filename was forcdeth-increase-max_interrupt_work.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: forcdeth: increase max_interrupt_work From: Joe Korty <joe.korty@xxxxxxxx> This eliminates the following often-generated warning from my 64 bit Opteron SMP test stand: eth0: too many iterations (6) in nv_nic_irq According to the web, the problem is that the forcedeth driver has a too-low value for max_interrupt_work. Grepping the kernel I see that forcedeth has the second lowest value of all ethernet drivers (ie, 6). Most are in the 20-40 range. So this patch increases this a bit, from 6 to 15 (at 15 forcedeth becomes the driver with third-lowest max_interrupt_work value). My test stand, which used to print out the above warnings repetitively whenever it was under heavy net load, no longer does so.
