commit 7b3b2432d42a54c174177ad5380a21449fce77ed
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=7b3b2432d42a54c174177ad5380a21449fce77ed

learn: Make it possible to parse "load" actions wider than 64 bits.
		
The implementation of the "learn" action now properly implements
specifications such as 0x20010db885a308d313198a2e03707348->NXM_NX_IPV6_DST
but the parser used in ovs-ofctl and elsewhere could not generate such
specifications.  This commit adds that support.

meta-flow: New functions for reading and writing generalized subfields.
		
The existing functions for reading and writing the values of subfields only
handle subfields up to 64 bits wide.  These new functions handle subfields
of any width.

Also update some existing comments.

It's the obvious counterpart to bitwise_zero().
