patch 'net/i40e/base: fix loop counter width in DCB parsing' has been queued to stable release 24.11.7

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/313d2488adc0e40ac0bae56c342380b8b06ca035

Thanks.

Luca Boccassi

Subject: [PATCH] net/i40e/base: fix loop counter width in DCB parsing

[ upstream commit 0693192a16bc2f4881461f54cf55ae9b8d0fcab5 ]

Loop counters in i40e_parse_cee_app_tlv() and
i40e_add_ieee_app_pri_tlv() are declared as u8 but compared against
numapps which is u32. If numapps exceeds 255 the counter wraps,
truncating the iteration. Widen the counters to u32.

Fixes: 166dceeeeafc ("i40e/base: add parsing for CEE DCBX TLVs")
Fixes: 0d9d27bb8684 ("i40e/base: prepare local LLDP MIB in TLV")
