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.

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.

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.

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.

Without this patch we can not access the PHY when the MAC is switched

through PHY registers.

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.
