Or Gerlitz says: ==================== Mellanox NIC drivers update, June 23 2015 This series has two fixes from Eran to his recent SRIOV counters work in mlx4 and few more updates from Saeed and Achiad to the mlx5 Ethernet code. All fixes here relate to net-next code, so no need for -stable. ==================== Signed-off-by: -

In order to save PCI BW consumed by TX CQEs and to reduce the amount of CPU cache misses caused by TX CQE reading, we request TX CQE generation only when skb->xmit_more=0. As a consequence of the above, a single TX CQE may now indicate the transmission completion of multiple TX SKBs. This also handles a problem introduced in commit b1b8105ebf41 "net/mlx5e: Support NETIF_F_SG" where we didn't ask for NOP completions while the driver didn't have the proper code to handle this case.

To save per-packet calculations, we use the following static mappings: 1) priv {channel, tc} to netdev txq (used @mlx5e_selec_queue()) 2) netdev txq to priv sq (used @mlx5e_xmit()) Thanks to these static mappings, no more need for a separate implementation of ndo_start_xmit when multiple TCs are configured. We believe the performance improvement of such separation would be negligible, if any. The previous way of dynamically calculating the above mappings required allocating more TX queues than actually used (@alloc_etherdev_mqs()), which is now no longer needed. Signed-off-by: -

Under SRIOV, the port rx/tx bytes/packets statistics should by read from the HW instead of using the PF netdevice SW accounting. This is needed in order to get the full port statistics and not just the PF own ones Signed-off-by:

This patch implements couple of fixes to support ACPI for RGMII/SGMII0/XFI interface of APM X-Gene SoC ethernet controller driver.

Below case causes mii bus probe failed: ifconfig eth0 down -> suspend/resume with Mega/fax mix off -> ifconfig eth0 up In i.MX6SX/i.MX7D chip, Mega/fast mix off feature is supported that means most of SOC power will be off including ENET MAC for power saving. Once ENET MAC power off, all initialized MAC registers reset to default, so in the case, it must init MAC prior to mii bus probe. Signed-off-by:

This particular BUG_ON condition was checking for attr set err in the COMMIT phase, which isn't expected (it's a driver bug if PREPARE phase is OK but COMMIT fails). But BUG_ON() is too strong for this case, so change to WARN(). BUG_ON() would be warranted if the system was corrupted beyond repair, but this is not the case here. Signed-off-by:

Add vlan dump support to switchdev port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how to show the vlans installed on the bridge and the device , but (until now) no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK msg.

Remove handling of tx_ring in prb_setup_retire_blk_timer for TPACKET_V3 because init_prb_bdqc is called only for zero tx_ring and thus prb_setup_retire_blk_timer for zero tx_ring only. And also in functon init_prb_bdqc there is no usage of tx_ring. Thus removing tx_ring from init_prb_bdqc. Signed-off-by:

This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by:

The mac settings like RGMII/RMII, speeds etc are done in the so called "General Register Files", contain numerous other settings as well and always seem to change between Rockchip SoCs. Therefore abstract the register accesses into a per-soc ops struct to make this reusable on other Rockchip SoCs. Signed-off-by:

The first iteration of the dwmac-rk support did access an intermediate clock directly below the pll selector. This was removed in a subsequent revision, but the clock and one invocation remained. This results in the driver trying to set the rate of a non-existent clock when the soc and not some external source provides the phy clock for RMII phys. So set the rate of the correct clock and remove the remaining now completely unused definition.
