patch 'net/bnxt/tf_core: fix TCAM manager data corruption' has been queued to stable release 23.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/10/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=f912142dc89ac8f14242b40e523ee192a0c46d55

Thanks.

[ upstream commit 0bee506e9ec6bca60111b63e631c84080b14aec2 ]

Max entries per session were not getting initialized
to 0, when the sessions were closed.
Reset max entries counter session when the session is initialized
