Subject: lpm: fix freeing memory
X-Git-Tag: spdx-start~5398
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c7e9d6a6ed90a022067f42727d5d1675a3f3df11;p=dpdk.git

lpm: fix freeing memory

The memory pointed by lpm->rules_tbl should also be freed
when memory malloc for tbl8 fails in rte_lpm_create_v1604( ).
And the memory pointed by lpm->tbl8 should also be freed
when the lpm object is freed in rte_lpm_free_v1604( ).

Fixes: f1f7261838b3 ("lpm: add a new config structure for IPv4")
