[dpdk-stable] patch 'net: define IPv4 IHL and VHL' has been queued to LTS release 18.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 09/03/19. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/e63b7033e41f7cf5e462a8301ca84b2ba9c30fd4

Thanks.

Kevin Traynor

Subject: [PATCH] net: define IPv4 IHL and VHL

[ upstream commit 2318d8d5456532e8022d324937a77a416b701d2b ]

Define IPv4 Minimum IHL and VHL according to rfc791 (see [1])

    "The Version field indicates the format of the
    internet header."

    "Internet Header Length (ihl) is the length of the
    internet header in 32 bit words, and thus points
    to the beginning of the data. Note that
    the minimum value for a correct header is 5."

[1] https://tools.ietf.org/html/rfc791
