-----------
inmates: e1000-demo: Hard-wire PHY address

All known e1000-compatible cards have their PHYs at address 1. Searching
for them does not work reliably, so simply hard-wire the address.

Log Message:
-----------
inmates: e1000-demo: Write RX tail only after enabling the queue

The 82575 ignores all writes prior to enabling the queue or the complete
receiver. Reorder writes, clearing the tail first - just in case.

inmates: e1000-demo: Fix FRCSPD bit definition for control register

It's bit 11, in fact. Bit 12 is FRCDPLX which is cleared on reset.

Log Message:
-----------
inmates: e1000-demo: Do not set ASDE bit

ASDE is apparently not needed on older NICs but caused troubles on newer
ones like 82575. Remove it.

Log Message:
-----------
inmates: e1000-demo: Enable queues explicitly

Newer NICs require us to enable the RX and TX queue. Although they
should be on after reset, at least the I350 refuses to work otherwise.
As the related bit is harmless or even unused on older NICs, do this
unconditionally (just like ipxe does).
