Subject: net/ice/base: fix tunnel destroy
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c7ff2213a5fe884d56adcd4a7b50ecd5810bebf2;p=dpdk.git

net/ice/base: fix tunnel destroy

The TCAM information in AQ command buffer is not correct when destroying
the tunnel entries. The TCAM count was always ONE even multiple entries
are destroyed, and the offset of TCAM memory was also incorrect.
This patch is to fix this issue.

Fixes: 884efe3ca1f3 ("net/ice/base: add VXLAN/generic tunnel management")
