After commit b6c5734db070 ("sctp: fix the handling of ICMP Frag Needed
for too small MTUs"), sctp_transport_update_pmtu would refetch pathmtu
from the dst and set it to transport's pathmtu without any check.
The new pathmtu may be lower than MINSEGMENT if the dst is obsolete and
updated by .get_ds
As Ido's suggestion, this patch is to add a selftest for directed
broadcast forwarding with vrf. Just note that it puts the h2 into
the main route space, so that ping_test could get echo_reply.

This patch implements the feature described in rfc1812#section-5.3.5.2
and rfc2644. It allows the router to forward directed broadcast when
sysctl bc_forwarding is enabled.
Note that this feature could be done by iptables -j TEE, but it would
cause some problems:
- target TEE's gateway param has
Patch 1/2 is the feature and 2/2 is the selftest. Check the changelog
on each of them to know the details.
v1->v2:
- fix a typo in changelog.
- fix an uapi break that Davide noticed.
- flush route cache when bc_forwarding is changed.
- add the selftest for this patch as Ido's suggestion.
The m88e1121 LED default configuration does not apply m88e151x.
So add a function to relpace m88e1121 LED configuration.

Need to set VEB eswitch mode only when sriov is enabled, and it should be

After we change the ipvlan mode from l3 to l2, or vice versa, we only
reset IFF_NOARP flag, but don't flush the ARP table cache, which will
cause eth->h_dest to be equal to eth->h_source in ipvlan_xmit_mode_l2().
Then the message will not come out of host.
