Move initialization of locks and lists to adapter allocation function.
Otherwise we might end up with some uninitialized locks, like e.g. the
erp locks which only will be inititialized if an error recovery thread
for an adapter will be started.

Some SCSI devices apparently get very confused if we try to use the
echo buffer on a non-DT negotiated bus (this mirrors the problems of
using PPR on non-LVD for some devices). The fix is to be far more
conservative about when we use an echo buffer. With this patch, we'll
now see what parameters are negotiated by the read only test, and only
look for an echo buffer if DT is negotiated.

ARMv6K CPUs have SEV (send event) and WFE (wait for event) instructions
which allow the CPU clock to be suspended until another CPU issues a
SEV, rather than spinning on the lock wasting power. Make use of these
instructions.
Note that WFE does not wait if an event has been sent since the last WFE
cleared the event status, so although it may look racy, the instruction
implementation ensures that these are dealt with.

Fixes BCSR accesses in the board setup/reset code. The registers are

without this patch after an rmmod, modprobe the card won't work anymore
until the next reboot.
This patch seem safe to apply for all cards as the bsd driver already do
that.
I had to add a timeout because strange things happen (issuecommand will
fail) if the card is already reseted (after a reboot).
PS : it seems there are missing reset when leaving monitor mode...

If using UDP over VLAN, with the skge driver there is a possibility
of generating an incorrect checksum. This is a unlikely occurrence
because it is only an issue on Yukon revision 0, and that revision
doesn't seem to exist on any current hardware (probably early prototype).

This patch fixes graceful stop timeout handling in PPC4xx EMAC driver.
Currently, when we stop TX/RX channels we just do some number of loops
without relying on actual spent time. This has finally bitten me on
one of our systems (heavy network traffic during start up, RX channel
is stopped several times to configure multicast list).
Graceful channel stop can take up to 1 frame time, so I've added
device specific timeout counter which depends on current link speed
and calls to udelay() to really wait required amount of time before
giving up.
