From fc0ecd4e9efcce5ccfda7a92ea87457e63be1d26 Mon Sep 17 00:00:00 2001 From: zhanghongyu Date: Thu, 13 Apr 2023 23:37:40 +0800 Subject: [PATCH] if_arp: add arphdr definition adapts to third-party code compilation. in the process of porting ConnMan, we encounter some situations where the structure is not defined, or the returned data types do not match the expectations. Refer to the common implementation of other systems and add relevant definitions.
