Put the offset of the CRC32C in csum_data instead of 0.
The virtio driver needs the offset to be stored in csum_data,
like in the case for UDP and TCP.

The virtio problem was reported by
Niu Zhixiong <kaiaixi@gmail.com>, who helped in debugging
and testing the patch.

Since 32-bit if_baudrate isn't enough to describe a baud rate of a 10 Gbit
interface, in the r241616 a crutch was provided. It didn't work well, and
finally we decided that it is time to break ABI and simply make if_baudrate
a 64-bit value. Meanwhile, the entire struct if_data was reviewed.

o Remove the if_baudrate_pf crutch.

o Make all fields of struct if_data fixed machine independent size. The
  notion of data (packet counters, etc) are by no means MD. And it is a
  bug that on amd64 we've got a 64-bit counters, while on i386 32-bit,
  which at modern speeds overflow within a second.

  This also removes quite a lot of COMPAT_FREEBSD32 code.

o Give 16 bit for the ifi_datalen field. This field was provided to
  make future changes to if_data less ABI breaking. Unfortunately the
  8 bit size of it had effectively limited sizeof if_data to 256 bytes.

o Give 32 bits to ifi_mtu and ifi_metric.
o Give 64 bits to the rest of fields, since they are counters.

__FreeBSD_version bumped.

Add MSI support to puc(9)

Add support for MSI interrupts in the puc(9) driver.  By default the driver
will prefer MSI interrupts to legacy interrupts.  A tunable,
hw.puc.msi_disable, has been added to force the allocation of legacy
interrupts.

Fix pw(8) deletion of group "username" on userdel even if group "username"
is not associated with user "username". E.g., user "foo" has primary group
"wheel" and is unassociated with group "foo", yet userdel would delete the
group "foo" when deleting user "foo" (despite the fact that user "foo" is
not associated with group "foo" in any way).

Patch committed with minor style(9) changes.

Replace 4.4BSD Lite's unix domain socket backpressure hack with a cleaner
mechanism, based on the new SB_STOP sockbuf flag.  The old hack dynamically
changed the sending sockbuf's high water mark whenever adding or removing
data from the receiving sockbuf.  It worked for stream sockets, but it never
worked for SOCK_SEQPACKET sockets because of their atomic nature.  If the
sockbuf was partially full, it might return EMSGSIZE instead of blocking.

The new solution is based on DragonFlyBSD's fix from commit
3a6117bbe0ed6a87605c1e43e12a1438d8844380 on 2008-05-27.  It adds an SB_STOP
flag to sockbufs.  Whenever uipc_send surpasses the socket's size limit, it
sets SB_STOP on the sending sockbuf.  sbspace() will then return 0 for that
sockbuf, causing sosend_generic and friends to block.  uipc_rcvd will
likewise clear SB_STOP.  There are two fringe benefits: uipc_{send,rcvd} no
longer need to call chgsbsize() on every send and receive because they don't
change the sockbuf's high water mark.  Also, uipc_sense no longer needs to
acquire the UIPC linkage lock, because it's simpler to compute the
st_blksizes.

There is one drawback: since sbspace() will only ever return 0 or the
maximum, sosend_generic will allow the sockbuf to exceed its nominal maximum
size by at most one packet of size less than the max.  I don't think that's
a serious problem.  In fact, I'm not even positive that FreeBSD guarantees a
socket will always stay within its nominal size limit.
