IIRC = "If I Recall Correctly".
I am basing my answer on code knowledge I gained a year or two back.

Just re-checked the code and confirmed. The flag names on
wccp2_service_info are the same for both hash and mask methods. What
they do is different and hard-coded into Squid.

For mask assignment the static mask of 0x00001741 is sent from Squid for
each of the fields you configure a flag for.

http://www.squid-cache.org/Doc/config/wccp2_service_info/

Examples of what you need for your earlier requested config (Sorry about
the line wrap):

  wccp2_service_info 80 protocol=tcp flags=src_ip_hash
priority=240 ports=80

with mask assignment method sets the mask to be 0x1741 on the packet
src-IP when protocol is TCP and dst-port 80.

  wccp2_service_info 90 protocol=tcp flags=dst_ip_hash
priority=240 ports=80

with mask assignment method sets the mask to be 0x1741 on the packet
dst-IP when protocol is TCP and dst-port 80.
