The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phydev in the private structure, and update the driver to use the one contained in struct net_device.

There are two generics functions phy_ethtool_{get|set}_link_ksettings, so we can use them instead of defining the same code in the driver. There was a check on CAP_NET_ADMIN in bfin_mac_ethtool_setsettings, but this check is already done in dev_ethtool, so no need to repeat it before calling the generic function.

alloc_workqueue replaces deprecated create_singlethread_workqueue(). A dedicated workqueue has been used since the workitem viz lp->txtimeout_reinit is involved in reinitialization if a TX timeout occurs, which is necessary to guarantee forward progress in packet processing. As a network device can be used during memory reclaim, the workqueue needs forward progress guarantee under memory pressure. WQ_MEM_RECLAIM has been set to ensure this. Since there is only a single work item, explicit concurrency limit is unnecessary here. Signed-off-by: NBhaktipriya Shridhar <bhaktipriya96@gmail.com> Signed-off-by: NDavid S.

commit 90017acc ("sctp: Add GSO support") didn't register SCTP GSO offloading for IPv6 and yet didn't put any restrictions on generating GSO packets while in IPv6, which causes all IPv6 GSO'ed packets to be silently dropped. The fix is to properly register the offload this time. Fixes: 90017acc ("sctp: Add GSO support") Signed-off-by: NMarcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: NDavid S.

Commit d46e416c missed to update some other places which checked for the socket being TCP-style AND Established state, as Closing state has some overlapping with the previous understanding of Established. Without this fix, one of the effects is that some already queued rx messages may not be readable anymore depending on how the association teared down, and sending may also not be possible if peer initiated the shutdown. Also merge two if() blocks into one condition on sctp_sendmsg().

Dongpo Li says: ==================== Add Hisilicon MDIO bus driver and FEMAC driver This patch set adds a Hisilicon MDIO bus driver and a Fast Ethernet MAC(FEMAC) driver. We also abstract a general interface "of_phy_get_and_connect" for PHY connect. User will have no bother with getting "phy-mode" and "phy-handle" any more. Changes in v1: - Pass private data structure instead of struct mii_bus in MDIO read and write operation. - Return the error which devm_clk_get() gives when MDIO probe. - Leave the clock unprepared and disabled on error when MDIO probe. - Abstract a general interface "of_phy_get_and_connect" for PHY connect. - Remove the "_reset" suffixes in "reset-names" property. - Enable tx per-packet interrupt when tx fifo full. - Remove pointless compatible and add SoC specific compatible. - Declare only one clock in MAC dts documentation. - Add standard unit suffixes for "phy-reset-delays". - Use a smaller NAPI poll weight 16 for our Fast Ethernet MAC. - Use phy_ethtool_{get|set}_link_ksettings for ethtool ops. - Use phydev from struct net_device in MAC driver. ==================== Signed-off-by: NDavid S.

TI_CPSW_PHY_SEL depended on TI_CPSW and was selected by the latter. So there is no reason to have this symbol visible. A further optimisation would be to put the code for both symbols into a single module which would allow to not export at least cpsw_phy_sel() and simplify the module load process.

In preparation for hardware offloading of ipmr/ip6mr we need an interface that allows to check (and later update) the age of entries. Relying on stats alone can show activity but not actual age of the entry, furthermore when there're tens of thousands of entries a lot of the hardware implementations only support "hit" bits which are cleared on read to denote that the entry was active and shouldn't be aged out, these can then be naturally translated into age timestamp and will be compatible with the software forwarding age. Using a lastuse entry doesn't affect performance because the members in that cache line are written to along with the age. Since all new users are encouraged to use ipmr via netlink, this is exported via the RTA_EXPIRES attribute. Also do a minor local variable declaration style adjustment - arrange them longest to shortest.

Some devices of the same type all export the same, random MAC address. This behavior has been seen on the ZTE MF910, MF823 and MF831, and there are probably more devices out there. Fix this by generating a valid random MAC address if we read a random MAC from device. Also, changed the memcpy() to ether_addr_copy(), as pointed out by checkpatch.

Nikolay Aleksandrov says: ==================== net: bridge: simplify receive path and consolidate forwarding paths This set tries to simplify the receive and forwarding paths. Patch 01 is a trivial style adjustment, patch 02 removes one conditional from the unicast fast path, patch 03 removes another conditional and more imporantly removes the skb0/skb2 ambiguity about locally receiving the skb and switches to a boolean called "local_rcv". Patch 04 is the most important change which consolidates the forwarding paths for locally originated and forwarded packets into __br_forward. This allows us to remove the function pointers giving a minor performance boost, more importantly it makes it much easier to reason about the forwarding path and reduces the code duplication that was needed when making changes. Also it allows the receive path to fully setup the environment prior to calling any forwarding functions (i.e. to properly set unicast, local_rcv and search for unicast/mcast dst). Functionally everything should stay the same after this set. I've done basic tests with unicast/multicast/broadcast Tx/Rx. Please review carefully. ==================== Signed-off-by: NDavid S.

Before this patch we had two flavors of most forwarding functions - _forward and _deliver, the difference being that the latter are used when the packets are locally originated. Instead of all this function pointer passing and code duplication, we can just pass a boolean noting that the packet was locally originated and use that to perform the necessary checks in __br_forward. This gives a minor performance improvement but more importantly consolidates the forwarding paths. Also add a kernel doc comment to explain the exported br_forward()'s arguments.

Currently if the packet is going to be received locally we set skb0 or sometimes called skb2 variables to the original skb. This can get confusing and also we can avoid one conditional on the fast path by simply using a boolean and passing it around. Thanks to Roopa for the name suggestion.
