[dpdk-stable] [PATCH 18.11 2/5] net/bnxt: fix UDP tunnel port removal

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

[ upstream commit c4ae7adafa23fb1121b96518a9b9b815288e680c ]

The HWRM supports only one global destination port for a tunnel type.
When port is stopped, driver deletes the UDP tunnel port configured
in the HW, but it does not update the counter which causes the
tunnel port addition to fail after port is started again.

Fixed to update the counter when tunnel port is deleted.

Fixes: 10d074b2022d ("net/bnxt: support tunneling")
