Maybe not, but it is documented in the relevant HowTo though.

You are making life too hard for yourself. The E21_ALT_IFPORT #define
is a value that is output to the card, and not something that is meant
to be changed by the end user. As it says in the HowTo, just use
the low bits of the mem_end boot argument, i.e.:
LILO: linux ether=0,0,0,1
(That is IRQ, i/o, mem_start, mem_end). Any non-zero mem_end value
will cause the driver to use the secondary port. If you are into
the module thing, then use xcvr=1 on the insmod line, which is also
documented in the howto, and in the file:
./linux/Documentation/networking/net-modules.txt
