turbo option in addition to the mode bits; otherwise if the current
channel is a turbo mode channel we'll form an invalid media setting
and the ifmedia_set operation in vap_attach will panic.
While here use C99-style initialization for an array indexed by mode;
this makes it consistent w/ other usage and avoids breakage if we
should ever change the set of modes.
is messing with the UDP tunnel. This means
that if two users actually tried to change the
tunnel port at the same time interesting things COULD
result, but its probably very unlikely to happen :-)
The TTY buffers used the standard <sys/queue.h> lists. Unfortunately
they have a big shortcoming. If you want to have a double linked list,
but no tail pointer, it's still not possible to obtain the previous
element in the list. Inside the buffers we don't need them. This is why
I switched to custom linked list macros. The macros will also keep track
of the amount of items in the list. Because it doesn't use a sentinel,
we can just initialize the queues with zero.
In its simplest form (the output queue), we will only keep two
references to blocks in the queue, namely the head of the list and the
last block in use. All free blocks are stored behind the last block in
use.
I noticed there was a very subtle bug in the previous code: in a very
uncommon corner case, it would uma_zfree() a block in the queue before
calling memcpy() to extract the data from the block.
o add bus shim for cfi driver
o add static mapping for CS0 (we map all 16M as the cfi driver doesn't
support demand mapping)
Note this needs some tweaking to work for 2358 boards which is why the
CAMBRIA config is not touched.
for slave addressing by using left-adjusted slave addresses (i.e.
xxxxxxx0b).
- Require the low bit of the slave address to always be zero in smb(4) to
help catch broken applications.
- Adjust some code in the IPMI driver to not convert the slave address for
SSIF to a right-adjusted address. I (or possibly ambrisko@) added this in
the past to (unknowingly) work around the bug in ichsmb(4).

are generated during the close() call(MT).
- Bugfix: Generate DRY event when sender is dry during subscription.
Only for 1-to-1 style sockets (RS/MT)

- Bugfix: Clear vtag entries correctly on expiration (MT).
- Bugfix: shutdown() indicates ENOTCONN when called for unconnected
1-to-1 style sockets (MT).
- Bugfix: In sctp Auth code (PL).

we, like TCP and UDP, move the checksum calculation
into the IP routines when there is no hardware support
we call into the normal SCTP checksum routine.
The next round of SCTP updates will use
this functionality. Of course the IGB driver needs
a few updates to support the new intel controller set
that actually does SCTP csum offload too.

- Make the NMI handler run on its own stack (TSS_IST2).
- Store the GSBASE value for each CPU just before the start of
each NMI stack, permitting efficient retrieval using %rsp-relative
addressing.
- For NMIs taken from kernel mode, program MSR_GSBASE explicitly
since one or both of MSR_GSBASE and MSR_KGSBASE can be potentially
invalid. The current contents of MSR_GSBASE are saved and restored
at exit.
- For NMIs handled from user mode, continue to use 'swapgs' to
load the per-CPU GSBASE.

the flag bits and the current base address), its length, and whether or not
it is enabled. Since this operation is not invasive, non-root users are
allowed to use it (unlike manual config register access which requires
root). The intention is that userland apps (such as Xorg) will use this
interface rather than dangerously frobbing the BARs from userland to
obtain this information.
- Add a new sub-mode to the 'list' mode of pciconf. The -b flag when used
with -l will now list all the active BARs for each device.
