BD_SUPPORT_FRAGS is preprocessor knob to allow partial reads in bioscd/biosdisk
level. However, we already have support for partial reads in bcache, and there
is no need to have duplication via preprocessor controls.
Note that bioscd/biosdisk interface is assumed to perform IO in 512B blocks,
so the only translation we have to do is 512 <-> native block size.

ZoL did the same mistake, and fixed it with separate commit 863522b1f9:
dsl_scan_scrub_cb: don't double-account non-embedded blocks
We were doing count_block() twice inside this function, once
unconditionally at the beginning (intended to catch the embedded block
case) and once near the end after processing the block.
The double-accounting caused the "zpool scrub" progress statistics in
"zpool status" to climb from 0% to 200% instead of 0% to 100%, and
showed double the I/O rate it was actually seeing.
This was apparently a regression introduced in commit 00c405b4b5e8,
which was an incorrect port of this OpenZFS commit:

While we're not super size constrained, the x86 BIOS /boot/loader has
to be less than about 520k-530k to be reliable. The LUA loader is at
this size today. -Oz saves 15-20% on the size, keeping us safely small
enough (comparable to where we were with the 4th loader). This will
also help with sjg's work on bringing in bearssl, though we may again
be looking for space in the LUA loader.

This is actually several different bugs:
- The code is not designed to handle inpcb deletion after interface deletion
- add reference for inpcb membership
- The multicast address has to be removed from interface lists when the refcount
goes to zero OR when the interface goes away
- decouple list disconnect from refcount (v6 only for now)
- ifmultiaddr can exist past being on interface lists
- add flag for tracking whether or not it's enqueued
- deferring freeing moptions makes the incpb cleanup code simpler but opens the
door wider still to races
- call inp_gcmoptions synchronously after dropping the the inpcb lock
Fundamentally multicast needs a rewrite - but keep applying band-aids for now.

The isonum_* functions are defined to take unsigend char* as an argument,

hashfilters. Two because the driver needs to look up a hashfilter by
its 4-tuple or tid.
A couple of fixes while here:
- Reject attempts to add duplicate hashfilters.
- Do not assume that any part of the 4-tuple that isn't specified is 0.
This makes it consistent with all other mandatory parameters that
already require explicit user input.

WPA: Ignore unauthenticated encrypted EAPOL-Key data
Ignore unauthenticated encrypted EAPOL-Key data in supplicant
processing. When using WPA2, these are frames that have the Encrypted
flag set, but not the MIC flag.
When using WPA2, EAPOL-Key frames that had the Encrypted flag set but
not the MIC flag, had their data field decrypted without first verifying
the MIC. In case the data field was encrypted using RC4 (i.e., when
negotiating TKIP as the pairwise cipher), this meant that
unauthenticated but decrypted data would then be processed. An adversary
could abuse this as a decryption oracle to recover sensitive information
in the data field of EAPOL-Key messages (e.g., the group key).
