Subject: [PATCH] net/i40e/base: fix potential out of bound array access
[ upstream commit 998c56772d0dc554c0209880d9394a0d14a18c74 ]
This is fix for klocwork issue where dcbcfg->numapps could
be greater than size of array (i.e dcbcfg->app[I40E_DCBX_MAX_APPS]).
The fix makes sure the array is not accessed past size of array
(i.e. I40E_DCBX_MAX_APPS).
Fixes: 166dceeeeafc ("i40e/base: add parsing for CEE DCBX TLVs")
