It's nowhere near that scary now.

the boot parameters from initarm first thing. parse_boot_param parses
the boot arguments and converts them to the /boot/loader metadata the
rest of the kernel uses. parse_boot_param is a weak alias to
fake_preload_metadata, which all the platforms use now, but may become
more extensive in the future.
Since it is a weak symbol, specific boards may define their own
parse_boot_param to interface to custom boot loaders.

ath_start() is called.
This (defaults to 10 frames) gives for a little headway in the TX ath_buf
allocation, so buffer cloning is still possible.
This requires a lot omre experimenting and tuning.
It also doesn't stop a node/TID from consuming all of the available
ath_buf's, especially when the node is going through high packet loss
or only talking at a low TX rate. It also doesn't stop a paused TID
from taking all of the ath_bufs. I'll look at fixing that up in subsequent
commits.

indx will never be -1 on error, as none of dupfdopen(), finstall() and
kern_capwrap() modifies it on error, but what is more important none of
those functions install and leave file at indx descriptor on error.
Leave an assert to prove my words.

This saves us the filedesc lock/unlock cycle, fhold()/fdrop() cycle and closes
a race between finstall() and dupfdopen().

it a bit:
- We can assert that only ENODEV and ENXIO errors are passed instead of
handling other errors.
- The caller always call finstall() for indx descriptor, so we can assume
it is set. Actually the filedesc lock is dropped between finstall() and
dupfdopen(), so there is a window there for another thread to close the
indx descriptor, but it will be closed in next commit.

If fdalloc() decides to grow fdtable it does it once and at most doubles
the size. This still may be not enough for sufficiently large fd. Use fd
in calculations of new size in order to fix this.
When growing the table, fd is already equal to first free descriptor >= minfd,
also fdgrowtable() no longer drops the filedesc lock. As a result of this there
is no need to retry allocation nor lookup.
Fix description of fd_first_free to note all return values.

growing "downward" (moving the start address down). First, an off by
one error caused the end address to be moved down an extra alignment
chunk unnecessarily. Second, when aligning the new candidate starting
address, the wrong bits were masked off.

* Create sc_mgmt_txbuf and sc_mgmt_txdesc, initialise/free them appropriately.
* Create an enum to represent buffer types in the API.
* Extend ath_getbuf() and _ath_getbuf_locked() to take the above enum.
* Right now anything sent via ic_raw_xmit() allocates via ATH_BUFTYPE_MGMT.
This may not be very useful.
* Add ATH_BUF_MGMT flag (ath_buf.bf_flags) which indicates the current buffer
is a mgmt buffer and should go back onto the mgmt free list.
* Extend 'txagg' to include debugging output for both normal and mgmt txbufs.
* When checking/clearing ATH_BUF_BUSY, do it on both TX pools.
Tested:
* STA mode, with heavy UDP injection via iperf. This filled the TX queue
however BARs were still going out successfully.
TODO:
* Initialise the mgmt buffers with ATH_BUF_MGMT and then ensure the right
type is being allocated and freed on the appropriate list. That'd save
a write operation (to bf->bf_flags) on each buffer alloc/free.
* Test on AP mode, ensure that BAR TX and probe responses go out nicely
when the main TX queue is filled (eg with paused traffic to a TID,
awaiting a BAR to complete.)

must be recalculated. The blk_check pass of suj checker explicitely marks
inodes which owned such blocks as needing block count adjustment. But
ino_adjblks() is only called by cg_trunc pass, which is performed before
blk_check. As result, the block use count for such inodes is left wrong.
This causes full fsck run after journaled run to still find inconsistencies
like 'INCORRECT BLOCK COUNT I=14557 (328 should be 0)' in phase 1.
Fix this issue by running additional adj_blk pass after blk_check, which
updates the field.

thing it was still used for was to set the "global default" password
hash. Since the stock auth.conf contained nothing but comments, the
global default was actually the first algorithm in crypt(3)'s list,
which happens to be DES; I take the fact that nobody noticed as proof
that it was not used outside of crypt(3).
The only other use in our tree was in the Kerberos support code in
in tinyware's passwd(1). I removed that code in an earlier commit;
it would not have compiled anyway, as it only supported Kerberos IV.
The auth_getval() function is now a stub that always returns NULL,
which has the same effect as a functional auth_getval() with an
empty auth.conf.
