The definition for netmask I find in that section is
Netmask (dotted quad or CIDR)

address field immediately above, but I don't know of anything else
that's consistent with CIDR notation.
I agree that this part of the manpage is in dire need of good wording.
I'd replace it with "Netmask (dotted quad or number of bits, eg 24)",
because that's how it actually works.
Mostly the netmask field should be considered a legacy interface.
Historically, the address was only the address, and the netmask was the
dotted-quad formatted netmask for that address. When ifupdown gained the
ability to specify the address field in address/bits format (in wheezy),
the netmask field was extended to also recognize cidr bits in addition
to dotted quad. (This also provides symmetry with the ipv6
representation, where dotted quad doesn't make sense.) With the new
address syntax the netmask field is fully redundant, but remains for
upgrades and compatibility with old scripts/etc.
