On older chips, the INI value differ in similar ways as cycpwr_thr1, so
convert it to absolute values as well.
Since the ANI algorithm is different here compared to the old
implementation (fewer steps, controlled at a different point in time),
it makes sense to use values similar to what would be applied for newer
chips, just without relying on INI defaults.

The table was copied from the ANI implementation of AR9300. It assumes
that the INI values contain a baseline value that is usable as reference
from which to increase/decrease based on the noise immunity value.
On older chips, the differences are bigger and especially AR5008/AR9001
are configured to much more sensitive values than what is useful.
Improve ANI behavior by reverting to the absolute values used in the
previous implementation (expressed as a simple formula instead of the
old table).

When brcm80211 firmware is not installed networking hangs.
A deadlock happens because we call ieee80211_unregister_hw()
from the .start callback of struct ieee80211_ops. When .start
is called we are under rtnl lock and ieee80211_unregister_hw()
tries to take it again.
Function call stack:
dev_change_flags()
__dev_change_flags()
__dev_open()
ASSERT_RTNL() <-- Assert rtnl lock
ops->ndo_open()
.ndo_open = ieee80211_open,
ieee80211_open()
ieee80211_do_open()
drv_start()
local->ops->start()
.start = brcms_ops_start,
brcms_ops_start()
brcms_remove()
ieee80211_unregister_hw()
rtnl_lock() <-- Here we deadlock
Introduced by:
commit 25b5632fb3
("brcmsmac: request firmware in .start() callback")
This patch fixes the bug by removing the call to brcms_remove()
and moves the brcms_request_fw() call to the top of the .start
callback to not initiate anything unless firmware is installed.

Currently a "r8185" integer variable is used as a boolean flag to
indicate whether the card is a rtl8185 or not.
Since now the driver supports only rtl8185 and rtl8180 cards, if
"r8185" variable is zero then the card is implicitly assumed to
be a rtl8180.
Now I'm preparing to add support for a third card type (rtl8187se).
This patch changes the "r8185" flag with an enum variable to
explicitly indicate which card type we have.
I'm submitting this this patch now, even if I still have to submit
other patches that not pertain with rtl8187se support, because
IMHO it's not worth rebasing them on the current code, using r8185
flag, and then changing them back again nearly immediately.
BTW if someone feels I really should do this, please tell me..

path, then we need to be able to handle and return failures.
And if they do allocations or mappings in the init command path,
then we need a cleanup function to free up that space at exit
time. So add blk_mq_free_commands() as the cleanup function.
