Since commit 3d7608e4 ("ARM: shmobile: bockw: remove legacy board file and config"), R-Car Gen1 SoCs are only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to match platform devices by name anymore, hence remove the corresponding platform_device_id entry. Protect sh_eth_set_rate_r8a777x() and r8a777x_data by #ifdef CONFIG_OF, as they're now referenced on DT platforms only.

Protect r8a7740_data by #ifdef CONFIG_OF as it's now referenced on DT platforms only. Move it to a more logical position, in front of the r8a777x support, so we can have a single #ifdef covering all r7s* and r8a* support soon. This requires moving a few helper functions, too.

The private slave queue and slave struct haven't been used for anything and aren't needed, this allows to reduce memory usage and simplify enslave/release. We can use netdev_for_each_lower_dev() to free the vrf ports when deleting a vrf device. Also if in the future a private struct is needed for each slave, it can be implemented via lower devices' private member (similar to how bonding does it).

This code is pretty confused. The variable name 'bytes_not_copied' clearly indicates that the programmer knew the semantics of copy_{to,from}_user, but then the return value is checked for being negative and used as a -Exxx return value. I'm not sure this is the proper fix, but at least we get rid of the dead code which pretended to check for access faults.

If ixgbevf is loaded while the corresponding PF interface is down and the driver assigns a random MAC address, that address can be overwritten with the value of hw->mac.perm_addr, which would be 0 at that point. To avoid this case we init hw->mac.perm_addr to the randomly generated address and do not set it unless we receive ACK from ixgbe.

This patch is the ixgbevf version of commit 8ac34f10 "ixgbe: Limit lowest interrupt rate for adaptive interrupt moderation to 12K" The same logic applies here as well as the same results since a netperf test will starve for memory in the time from one Tx interrupt to the next.

Commit 46e8a249423ff "bnx2x: Add FW 7.13.1.0" added said .bin FW to linux-firmware; This patch incorporates the FW in the bnx2x driver. This introduces 2 fixes/enhancements: - In some management protocols there are outer-vlan configurations that can be dynamically changed while device is running. This fixes some corner cases where such a change did not take effect. - Prevent VFs from sending MAC control frames; FW would treat a VF sending such a packet as malicious and block any further communication done by the VF.

Today, port statistics are being presented when using `ethool -S' only for single-function devices, but there are some port statistics which are crucial for analyzing bottle-necks. E.g., HW Rx discards due to lack of buffer space [when device isn't handling ingress traffic fast enough]. Judging the pros and cons, it was decided that in-order to better support automatic dump-gathering tools, bnx2x should no longer hide those stats. This leaves only VFs lacking the port statistics.

NAPI drivers no longer need to observe a particular protocol to benefit from busy polling (CONFIG_NET_RX_BUSY_POLL=y) napi_hash_add() and napi_hash_del() are automatically called from core networking stack, respectively from netif_napi_add() and netif_napi_del() This patch depends on free_netdev() and netif_napi_del() being called from process context, which seems to be the norm. Drivers might still prefer to call napi_hash_del() on their own, since they might combine all the rcu grace periods into a single one, knowing their NAPI structures lifetime, while core networking stack has no idea of a possible combining. Once this patch proves to not bring serious regressions, we will cleanup drivers to either remove napi_hash_del() or provide appropriate rcu grace periods combining.
