From: Fan Zhang Date: Thu, 20 Dec 2018 11:56:43 +0000 (+0000) Subject: crypto/aesni_mb: rename files X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e82d0df613428b6572bf80297c99e25a74e9c7fb;p=dpdk.git crypto/aesni_mb: rename files This patch renames the rte_aesni_mb_pmd*.c to rte_aesni_mb_pmd*_compat.c to indicate those files are for compatible with older versoin of intel-ipsec-mb library only.
