2007-07-16myri10ge: Remove nonsensical limit in the tx done routineBrice Goglin
Remove nonsensical limit in the tx done routine. Specifically, the loop will always terminate after processing <= 1 rings worth of frames, as the mcp index is not refetched, so the removed conditional could never be true.

2007-06-12myri10ge: report when the link partner is running in Myrinet modeBrice Goglin
Since Myri-10G boards may also run in Myrinet mode instead of Ethernet, add a message when we detect that the link partner is not running in the right mode. Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-06-12myri10ge: limit the number of recoveriesBrice Goglin
Limit the number of recoveries from a NIC hw watchdog reset to 1 by default. It enables detection of defective NICs immediately since these memory parity errors are expected to happen very rarely (less than once per century*NIC).

2007-05-08myri10ge: replace the chipset whitelist with firmware autodetectionBrice Goglin
Remove the aligned-completion whitelist, and replace it by using the 1.4.16 firmware's auto-detection features to choose which firmware to load. The driver now loads the aligned firmware, performs a MXGEFW_CMD_UNALIGNED_TEST, and falls back to using the unaligned firmware if: - The firmware is too old (ie, MXGEFW_CMD_UNALIGNED_TEST is an unknown command). - The MXGEFW_CMD_UNALIGNED_TEST returns MXGEFW_CMD_ERROR_UNALIGNED, meaning that it has seen an unaligned completion during the DMA test.

2007-05-08myri10ge: fix restoring of multicast list after resetBrice Goglin
Don't count on whatever implementation artifact preserves the multicast list across a reset cmd, and setup multicast filtering as part of our reset routine. The setting of allmulti when adopting firmware with the rx-filter broadcast bug is also moved into the multicast setup routine where it belongs.

2007-04-25[SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}Arnaldo Carvalho de Melo

2007-04-25[TCP]: Introduce tcp_hdrlen() and tcp_optlen()Arnaldo Carvalho de Melo
The ip_hdrlen() buddy, created to reduce the number of skb->h.th-> uses and to avoid the longer, open coded equivalent. Ditched a no-op in bnx2 in the process.

2007-04-11myri10ge: fix management of the firmware 4KB boundary crossing restrictionBrice Goglin
Simpler way of dealing with the firmware 4KB boundary crossing restriction for rx buffers. This fixes a variety of memory corruption issues when using an "uncommon" MTU with a 16KB page size. Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-03-28myri10ge: correctly detect when TSO should be usedBrice Goglin
Correctly detect when TSO should be used on transmit by looking at the skb->gso_size rather than seeing if the frame was larger than our MTU. The old method causes problems when a host with a large (jumbo) MTU is sending to a host with a small (standard) MTU.

2007-01-18myri10ge: check that we can get an irqBrice Goglin

2006-12-26myri10ge: no need to save MSI and PCIe state in the driverBrice Goglin
The PCI MSI and express state are already saved and restored by the current versions of pci_save_state/pci_restore_state. Therefore it is no longer necessary for the driver to do it.

2006-12-26myri10ge: make msi configurable at runtime through sysfsBrice Goglin
Now that IRQ are requested is called on open() and freed on close(), we can safely switch from/to MSI without unloading the module. We are guaranteed to correctly free IRQ even if the sysfs file got written in the meantime since the MSI initialization is stored in mgp->msi_enabled.

2006-12-26myri10ge: move request_irq to myri10ge_openBrice Goglin
Request IRQ in myri10ge_open() and free in close() instead of probe() and remove() to eliminate potential race between the watchdog and the interrupt handler. Additionaly, the interrupt handler won't get called on shared irq anymore when the interface is down. Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-12-26myri10ge: match number of save_state and restoreBrice Goglin
Since pci_save_state() pushes MSI and PCIe states on a kind of stack, myri10ge saving the state in advance for parity recovery will push the state again on the stack on suspend. This leads to some memory leak. We add a couple additional calls to save_state and restore_state so that we don't leak anymore. For the future, we are thinking of a better way to recover from parity error without using pci_save_state(). Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-12-11[PATCH] myri10ge: fix big_bytes in case of vlan framesBrice Goglin
Fix sizing of big_bytes in the case of vlan frames. The 4 VLAN_HLEN bytes were omitted, leading to sizing the big buffer 4 bytes smaller than it should be. Due to how rx buffers are carved from pages, this was harmless for the common (9000, 1500) byte MTUs, but could lead to data corruption for some MTUs.
