  Changed paths:
    M lib/odp-util.c

  Log Message:
  odp-util: Use flexible sized buffer to hold Geneve options.

The 'mask' buffer in parse_odp_action() is supposed to always be big
  /* 'mask' is big enough to hold any key. */

Geneve options can be really big and the comment was wrong.  In addition,
the user might supply more options than can really fit in any case, so
we might as well just use a stub.
