This change merges the ATR table reinitialization into the service task. This is yet another opportunity to avoid any race conditions as we don't want to be attempting to reinitialize the table during a possible reset. In addition this change adds a counter for table reinitialization so that it can be tracked as part of the regular statistics. Signed-off-by:

Introduce buffered read/writes which greatly improves performance on parts with large EEPROMs. Previously reading/writing a word requires taking/releasing of synchronization semaphores which adds 10ms to each operation. The optimization is to read/write in buffers, but make sure the semaphore is not held for >500ms according to the datasheet. Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is used to discover the EEPROM size when needed and keeps the result in word_page_size for the rest of the run time. Use buffered reads for ethtool -e. Signed-off-by:

This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated. Tested: make allyesconfig on x86_64 + e1000e/bnx2x work Signed-off-by:

This change fixes several issues found in ntuple filtering while I was doing the ATR refactor. Specifically I updated the masks to work correctly with the latest version of ethtool, I cleaned up the exception handling and added detailed error output when a filter is rejected, and corrected several bits that were set incorrectly in ixgbe_type.h. The previous version of this patch included a printk that was left over from me fixing the filter setup. This patch does not include that printk. Signed-off-by:

This change cleans up the layout of the flow director data, and the algorithm used to calculate the hash resulting in a 35x / 3500% performance increase versus the old flow director hash computation. The overall effect is only a 1% increase in transactions per second though due to the fact that only 1 packet in 20 are actually hashed upon. TCP_RR before: Socket Size Request Resp. Elapsed Trans.

When disable the Rx logic globally, we would also want to disable the per Rx queue receive logic by per queue Rx control register RXDCTL so no more DMA is happening from the packet buffer to the receive buffer associated with the Rx ring, before we start unmapping Rx ring receive buffer. The hardware may take max of 100us before the corresponding Rx queue is really disabled. Added ixgbe_disable_rx_queue() for this purpose. Signed-off-by:

RSC will flush its descriptors every time the interrupt throttle timer expires. In addition there are known issues with RSC when the rx-usecs value is set too low. As such we are forced to clear the RSC_ENABLED bit and reset the adapter when the rx-usecs value is set too low. However we do not need to clear the NETIF_F_LRO flag because it is used to indicate that the user wants to leave the LRO feature enabled, and in fact with this change we will now re-enable RSC as soon as the rx-usecs value is increased and the flag is still set.

This change places a netdev pointer directly into the ring structure. This way we can avoid having to determine which netdev we are supposed to be using and can just access the one on the ring directly. As a result of this change further collapse of the code is possible by dropping the adapter from ixgbe_alloc_rx_buffers, and the netdev pointer from ixgbe_xmit_frame_ring_adv and ixgbe_maybe_stop_tx.

Current ixgbe stats have following problems : - Not 64 bit safe (on 32bit arches) - Not safe in ixgbe_clean_rx_irq() : All cpus dirty a common location (netdev->stats.rx_bytes & netdev->stats.rx_packets) without proper synchronization. This slow down a bit multiqueue operations, and possibly miss some updates. Fixes : Implement ndo_get_stats64() method to provide accurate 64bit rx|tx bytes/packets counters, using 64bit safe infrastructure. ixgbe_get_ethtool_stats() also use this infrastructure to provide 64bit safe counters.

In latest changes about 64bit stats on 32bit arches, [commit 28172739 (net: fix 64 bit counters on 32 bit arches)], I missed ixgbe uses a bit of magic in its ixgbe_gstrings_stats definition.

There is a small possibility that a reader gets incorrect values on 32 bit arches. SNMP applications could catch incorrect counters when a 32bit high part is changed by another stats consumer/provider. One way to solve this is to add a rtnl_link_stats64 param to all ndo_get_stats64() methods, and also add such a parameter to dev_get_stats(). Rule is that we are not allowed to use dev->stats64 as a temporary storage for 64bit stats, but a caller provided area (usually on stack) Old drivers (only providing get_stats() method) need no changes.
