net: sctp: rfc4443: do not report ICMP redirects to user space

Adapt the same behaviour for SCTP as present in TCP for ICMP redirect
messages. For IPv6, RFC4443, section 2.4. says:

  ...
  (e) An ICMPv6 error message MUST NOT be originated as a result of
      receiving the following:
  ...
       (e.2) An ICMPv6 redirect message [IPv6-DISC].
  ...

Therefore, do not report an error to user space, just invoke dst's redirect
callback and leave, same for IPv4 as done in TCP as well. The implication
w/o having this patch could be that the reception of such packets would
generate a poll notification and in worst case it could even tear down the
whole connection. Therefore, stop updating sk_err on redirects.

Ben Hutchings says:

====================
Some bug fixes and future-proofing for the recently added SFC9120
support:

1. Minimal support for the 40G configuration.
2. Disable the incomplete PTP/hardware timestamping support.
3. Reset MAC stats properly after a firmware upgrade.
4. Re-check the datapath firmware capabilities after the controller is
reset.

Clock 180 corresponds to 'spdif1_podf' and this clock is getting registered

Fix it, by properly registering the 'spdif1_pred' clock, which should not

KVM: mmu: allow page tables to be in read-only slots

Page tables in a read-only memory slot will currently cause a triple
fault because the page walker uses gfn_to_hva and it fails on such a slot.

OVMF uses such a page table; however, real hardware seems to be fine with
that as long as the accessed/dirty bits are set.  Save whether the slot
is readonly, and later check it when updating the accessed and dirty bits.
