Add newline to `Interface disabled' printf and clean up formatting.
Change packet read/write code to align all reads and writes into
memory to an appropriate boundary for the I/O size. This also fixes
a bug where the trailing unaligned bytes (1-3 of them) would be
put in an additional mbuf even if there was enough space for them
in the one we were currently filling.
This has been tested on a 3c905 in an Alpha (32-bit I/O, alignment
required), a 3c905 in an i386 (32-bit I/O, alignment not required)
and a 3c509 in an i386 (16-bit I/O, alignment not required). It
should be tested on a 3c509 in an Alpha with an ISA bus, if somone
can manage to get the two items together.
There are still some bugs in the driver relating to initialisation;
on my Alpha with a 3c905 you need to do an `ifconfig ep0 down;
ifconfig ep0 up' after the initial ifconfig to make it start working.
Apparently there are also some problems with a 3c579 in an i386,
although a 3c905 in an i386 works just fine.
