The DL100xx cards have 24k of packet memory, not 16k. Use it for them

and update comments about original patches doing this and it not
working.  It works for both the DL10019 and DL10022 based cards that I
have.  It really helps the DL10019 cards, since they were using 8k
instead of the normal 16k that regular NE-2000 cards help.

# Note to self: need to provide a common routine to setup memory
# parameters.
