When adding a new vxlan device to an "underlying carrier" (here: dst->remote_ifindex), the MTU size assigned to the vxlan device is the MTU at setup time of the carrier - needed headroom, when adding a vxlan device w/o explicit carrier, then it defaults to 1500. In case of an explicit carrier that supports jumbo frames, we currently cannot change vxlan MTU via ip(8) to > 1500 in post-setup time, as vxlan driver uses eth_change_mtu() as default method for manually setting MTU. Hence, use a custom implementation that only falls back to eth_change_mtu() in case we didn't use a dev parameter on device setup time, and otherwise allow a max MTU setting of the carrier incl. adjustment for headroom.

In commit 93b36cf3 ("ipv6: support IPV6_PMTU_INTERFACE on sockets") I made a horrible mistake to add ip6_sk_accept_pmtu to the generic sctp_icmp_frag_needed path. This results in build warnings if IPv6 is disabled which were luckily caught by Fengguang's kbuild bot. But it also leads to a kernel panic IPv4 frag-needed packet is received.

OMAP's ti_hecc driver is used to support the CAN controller on many omap2plus SoCs (OMAP2430, OMAP3, OMAP4, OMAP5 and AM335x), so it's wrong to make this depend on OMAP3 only. Take an extra step, to get wider build coverage, and make the driver depend on ARM.

Hauke Mehrtens says: ==================== b44: add support for external PHY This adds support for an external phy connected to the mac controlled by b44. This is used on home routers of the BCM47xx line where this MAC core was used and is contended to an external switch core through MII. These patches are in OpenWrt for some time and are tested by different users with different devices. The publicly available Programmer's Reference Guide for some of these chips help making this patch it would be nice to have such a documentation for more Broadcom Chips like some SoCs. https://www.broadcom.com/collateral/pg/440X-PG02-R.pdf ==================== Signed-off-by: David S.

The ADM6996L switch and some Broadcom switches with two MII interfaces like the BCM5325F connected to two MACs on the SoC, used on some routers do not return a valid value when reading the PHY id register and Linux thinks there is no PHY at all, but that is wrong. This patch registers a fixed phy in the arch code and then searches it when there is no other phy in the Ethernet driver code. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S.

Most of the older home routers based on the Broadcom BCM47XX SoC series are using a MAC that is supported by b44. On most of these routers not the internal PHY of this MAC core is used, but a switch sometimes on an external chip or integrated into the same SoC as the Ethernet core. For this switch a special PHY driver is needed which should not be integrated into b44 as the same switches are also used by other Broadcom home networking SoCs which are using different Ethernet MAC drivers. This was tested with the b53 switch driver which is currently on its way to mainline. If the internal PHY is not used, b44 will now search on the MDIO bus for a phy and use the Linux phylib subsystem to register a driver. Support for the internal PHY must stay here, because there are some device which are suing the internal phy. With this patch we scan the mdio bus when the sprom or nvram says that the PHY address is 30, if a PHY was found at this address b44 uses it. This was tested with a BCM4704, BCM4712 and BCM5354.

The PHY address 30 means there is no local PHY, but there could be an external PHY like a switch connected via MII. This is the case on most embedded home routers where this driver is used. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S. Miller <davem@davemloft.net>

Hauke Mehrtens authored
The Ethernet core supported by b44 supports an internal PHY integrated into the mac core, which is supported by the b44 driver and an external PHY to which the mac core is connected. This external PHY could be a switch connected through MII, which is often the case when this core is used on home routers. The usage of an external PHY was assumed when the PHY address 30 was used and an internal PHY was assumed when the PHY address was different. To verify that b44_phy_reset() was called and checked if it worked, otherwise PHY address 30 was assumed, an external PHY. It is better to check the register which says which PHY is connected to the MAC instead of checking the PHY address. The interface to an external PHY was only activated when this register was set. This also changes B44_FLAG_INTERNAL_PHY to B44_FLAG_EXTERNAL_PHY, it is easier to check. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S. Miller <davem@davemloft.net>

Willem noticed a TCP_RR regression caused by TCP autocorking on a Mellanox test bed. MLX4_EN_TX_COAL_TIME is 16 us, which can be right above RTT between hosts. We can receive a ACK for a packet still in NIC TX ring buffer or in a softnet completion queue. Fix this by always pushing the skb if it is at the head of write queue. Also, as TX completion is lockless, it's safer to perform sk_wmem_alloc test after setting TSQ_THROTTLED. erd:~# MIB="MIN_LATENCY,MEAN_LATENCY,MAX_LATENCY,P99_LATENCY,STDDEV_LATENCY" erd:~# ./netperf -H remote -t TCP_RR -- -o $MIB | tail -n 1 (repeat 3 times) Before patch : 18,1049.87,41004,39631,6295.47 17,239.52,40804,48,2912.79 18,348.40,40877,54,3573.39 After patch : 18,22.84,4606,38,16.39 17,21.56,2871,36,13.51 17,22.46,2705,37,11.83 Reported-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Fixes: f54b3111 ("tcp: auto corking") Signed-off-by: David S.

There's no need anymore to call phy_init_hw() to reset/resume the PHY from the driver, as the call chain in phylib already has reached it, and so reset/resumed the PHY (even resuming it twice). This duplicate reset is not only needless, it e.g. clears the PHY's interrupt enables just setup by phylib and so prevents the expected IRQs from the PHY.
