2007-10-10[ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik
For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.

2007-10-10[PATCH] drivers/net: remove superfluous memsetMariusz Kozlowski
This patch covers something like this: dev = alloc_*dev(... ... priv = netdev_priv(dev); memset(priv, 0, sizeof(*priv)); The memset() here is superfluous. alloc_netdev() uses kzalloc() to allocate needed memory so there is no need to zero the priv region twice.

2007-10-10[NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger
Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted. Integrated Stephen's follow-on kerneldoc additions, and restored poll_list handling to the old style to fix mutual exclusion issues. -DaveM ] Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.

2007-08-25myri10ge: use pcie_get/set_readrqBrice Goglin
Based on a patch from Peter Oruba, convert myri10ge to use pcie_get_readrq() and pcie_set_readrq() instead of our own PCI calls and arithmetics. These driver changes incorporate the proposed PCI-X / PCI-Express read byte count interface. Reading and setting those values doesn't take place "manually", instead wrapping functions are called to allow quirks for some PCI bridges.

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.
