patch 'net/ixgbe/base: fix PF link state request size' has been queued to stable release 24.11.4

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/26/25. 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

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/47b00e6f6ad34672a136383757d48c09320a73a3

Subject: [PATCH] net/ixgbe/base: fix PF link state request size

[ upstream commit 82ff0aa59735fefa6e9e9daf77ea87da5b68fabd ]

Currently, when requesting PF link state over VF mailbox, the buffer sized
3 dwords is allocated. However, the `ixgbevf_write_msg_read_ack` function
is actually called with buffer size of 6 dwords. This leaves an admittedly
remote possibility of buffer overrun. Fix by adjusting requested size to 3.

Bugzilla ID: 1801
Fixes: adbd71030575 ("net/ixgbe/base: fix link status for E610")
