2008-10-16[netdrvr] myri10ge, ixgbe: remove broken select INTEL_IOATDMAJeff Garzik
We cannot select INTEL_IOATDMA in Kconfig as soon as MYRI10GE or IXGBE is enabled since the former is not available on all architectures.

Add multi-slice/MSI-X support. By default, a single slice (and the normal firmware) are used.

2008-05-13myri10ge: fix the number of interrupt slotsBrice Goglin
Fix a long-standing bug/misunderstanding between the driver and the firmware. The size of the interrupt queue must be set to the number of rx slots (big + small), and it should never have been a tunable. Setting it too small results in chaos.

2008-05-13myri10ge: increase and fix handoff timeoutBrice Goglin
Increase the handoff timeout to 512ms so as to give the aeluros based NICs sufficient time to handoff without relying on the msleep() being sloppy, and accidentally sleeping way longer than the 20ms we specified in 20 separate 1ms sleeps.

2008-01-08[NET]: Do not check netif_running() and carrier state in ->poll()David S. Miller
Drivers do this to try to break out of the ->poll()'ing loop when the device is being brought administratively down. Now that we have a napi_disable() "pending" state we are going to solve that problem generically. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-12-05[LRO]: fix lro_gen_skb() alignmentAndrew Gallatin
Add a field to the lro_mgr struct so that drivers can specify how much padding is required to align layer 3 headers when a packet is copied into a freshly allocated skb by inet_lro.c:lro_gen_skb(). Without padding, skbs generated by LRO will cause alignment warnings on architectures which require strict alignment (seen on sparc64). Myri10GE is updated to use this field.

2007-11-01Fix myri10ge NAPI oops & warningsAndrew Gallatin
When testing the myri10ge driver with 2.6.24-rc1, I found that the machine crashed under heavy load: Unable to handle kernel paging request at 0000000000100108 RIP: [<ffffffff803cc8dd>] net_rx_action+0x11b/0x184 The address corresponds to the list_move_tail() in netif_rx_complete(): if (unlikely(work == weight)) list_move_tail(&n->poll_list, list); Eventually, I traced the crashes to calling netif_rx_complete() with work_done == budget. From looking at other drivers, it appears that one should only call netif_rx_complete() when work_done < budget. To fix it, I changed the test in myri10ge_poll() so that it refers to to work_done rather than looking at the rx ring status. If work_done is < budget, then that implies we have no more packets to process. Any races will be resolved by the NIC when the write to irq_claim is made. In myri10ge_clean_rx_done(), if we ever exceeded our budget, it would report a work_done one larger than was acutally done. This is because the increment was done in the conditional, so work_done would be incremented regardless of whether or not the test passed or failed. This would lead to the WARN_ON_ONCE(work > weight); warning in net_rx_action triggering. I've moved the increment of work_done inside the loop. Note that this would only be a problem when we had exceeded our budget. Signed off by: Andrew Gallatin <gallatin@myri.com> Andrew Gallatin Myricom Inc Signed-off-by: Jeff Garzik <jeff@garzik.org>
