[ovs-dev] [PATCH ovn v3 0/5] Implement matching expressions for OVN.

[Ben Pfaff]

The syntax of matching expressions supported here is documented in ovn(5),
which I've made available (along with the rest of the OVS docs for this
branch) at http://benpfaff.org/~blp/dist-docs, e.g. specifically
http://benpfaff.org/~blp/dist-docs/ovn.5.pdf

v1->v2: Drop patch 1 because it was applied.  Rebase because there was now
  a small patch reject in the original series.
v2->v3: New patch 5 to add basic support for string fields in conversion
  to flows.  (This patch could optionally be squashed into patch 4.)

Pfaff (5):
  lex: New lexical analyzer module for use in OVN.
  util: Add more bitwise operations.
  meta-flow: Add new functions for subvalues.
  expr: New module for Boolean expressions on fields, for use in OVN.
  expr: Support string fields in expr_to_matches().
