    "content": "From: Joe Korty <joe.korty@ccur.com>\n\nThis eliminates the following often-generated warning from my 64 bit\nOpteron SMP test stand:\n\n\teth0: too many iterations (6) in nv_nic_irq\n\nAccording to the web, the problem is that the forcedeth driver has a\ntoo-low value for max_interrupt_work.  Grepping the kernel I see that\nforcedeth has the second lowest value of all ethernet drivers (ie, 6). \nMost are in the 20-40 range.  So this patch increases this a bit, from 6\nto 15 (at 15 forcedeth becomes the driver with third-lowest\nmax_interrupt_work value).\n\nMy test stand, which used to print out the above warnings repetitively\nwhenever it was under heavy net load, no longer does so.\n\nSigned-off-by: Joe Korty <joe.korty@ccur.com>\nCc: Ayaz Abdulla <aabdulla@nvidia.com>\nCc: Jeff Garzik <jeff@garzik.org>\nSigned-off-by: Andrew Morton <akpm@linux-foundation.org>\n---\n\n drivers/net/forcedeth.c |    2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)",
