Hi Ben,
I believe that the revised patch below addresses the concerns that
you raised above. I have taken the uint16_t + struct netdev_stats
approach that you suggested.

ofp-msgs: Open Flow 1.1 and 1.2 Port Status Messages
This allows for encoding and decoding Open Flow 1.1 and 1.2 Port Stats
Request and Reply message
Signed-off-by: Simon Horman <horms at verge.net.au>
---
v14.1
* Add and make use of struct ofputil_port_stats,
a generic host-byte-order representation of port status replies
* Refactor and do not add new calls to abort()
* Fix typos in several helper function names
* Fix code-style problems
* Remove unnecessary 'noise' changes
v14
* Manual rebase
v13
* Merge the following patches
- ofp-msgs: Split OFPRAW_OFPST_PORT_{REQUEST,REPLY}
- ovs-ofctl: Teach dump-ports about Open Flow 1.1 & 1.2
- ofp-util: Allow encoding of Open Flow 1.1 & 1.2 Port Statistics Reply Messages
- ofp-print: Allow printing of Open Flow 1.1 & 1.2 Port Reply Messages
- ofp-util: Allow decoding of Open Flow 1.1 & 1.2 Port Status Request Messages
- ofp-print: Allow printing of Open Flow 1.1 & 1.2 Port Status Request Messages
* Move encoding and decoding into a helper functions
v12
* No change
v11
* No change
v10
* No change
v9
* Update description - this only prepares for both encoding and decoding
* Add ofp-print test
* Make use of enum ofp_version
* Correct printing of port number for Open Flow 1.0
* Replace UINT64_MAX with htonll(UINT64_MAX) in ofp_print_port_stat()
to correct byte-order problem detected by sparse
v8
* Manual rebase
* Make use of enum ofp_version
* Add ofp-print test
v7
* Omitted
v6
* No change
v5
* No change
v4
* Initial post
