Various boot loaders go to various extents to thwart the initrd detection
logic (mostly on account of not being able to be bothered with adhering
to the established boot ABI), so we make the detection logic a bit more
robust. This makes it possible to work around the SDK7786's firmware's
attempts to thwart compressed image booting. Victory is mine.

With fa35b4926, I broke a lot of PNP resource assignment. That commit made
PNPACPI include bridge windows as PNP resources, and PNP resource assignment
treats any enabled overlapping PNP resources as conflicts. Since PCI host
bridge windows typically include most of the I/O port space, this makes PNP
port assigments fail.
The PCI host bridge driver will eventually use those PNP window resources,
so we should make PNP ignore them when checking for conflicts.

I noticed when I added support for IPV6_DONTFRAG that if you set
IPV6_RECVERR and tried to send a UDP packet larger than 64K to an
IPv6 destination, you'd correctly get an EMSGSIZE, but reading from
MSG_ERRQUEUE returned the incorrect address in the cmsg:
struct msghdr:
msg_name 0x7fff8f3c96d0
msg_namelen 28
struct sockaddr_in6:
sin6_family 10
sin6_port 7639
sin6_flowinfo 0
sin6_addr ::ffff:38.32.0.0
sin6_scope_id 0 ((null))
It should have returned this in my case:
struct msghdr:
msg_name 0x7fffd866b510
msg_namelen 28
struct sockaddr_in6:
sin6_family 10
sin6_port 7639
sin6_flowinfo 0
sin6_addr 2620:0:a09:e000:21f:29ff:fe57:f88b
sin6_scope_id 0 ((null))
The problem is that ipv6_recv_error() assumes that if the error
wasn't generated by ICMPv6, it's an IPv4 address sitting there,
and proceeds to create a v4-mapped address from it.
Change ipv6_icmp_error() and ipv6_local_error() to set skb->protocol
to htons(ETH_P_IPV6) so that ipv6_recv_error() knows the address
sitting right after the extended error is IPv6, else it will
incorrectly map the first octet into an IPv4-mapped IPv6 address
in the cmsg structure returned in a recvmsg() call to obtain
the error.

The ->writepages writeback_control is not still valid in the writepages
completion. We were touching it solely to adjust pages_skipped when there
was a writeback error (EIO, ENOSPC, EPERM due to bad osd credentials),
causing an oops in the writeback code shortly thereafter. Updating
pages_skipped on error isn't correct anyway, so let's just rip out this
(clearly broken) code to pass the wbc to the completion.

This change increases the RX fifo size to 36K for standard frames and
decreases the TX fifo size to 4K. The reason for this change is that on
slower systems the RX is much more likely to backfill and need space than
the TX is. As long as the TX fifo is twice the size of the MTU we should
have more than enough TX fifo.
