From: Xie He Date: Fri, 28 Aug 2020 07:07:52 +0000 (-0700) Subject: drivers/net/wan/hdlc_cisco: Add hard_header_len X-Git-Tag: v5.10.7~1718^2~17 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1a545ebe380bf4c1433e3c136e35a77764fda5ad;p=platform%2Fkernel%2Flinux-rpi.git drivers/net/wan/hdlc_cisco: Add hard_header_len This driver didn't set hard_header_len. This patch sets hard_header_len for it according to its header_ops->create function. This driver's header_ops->create function (cisco_hard_header) creates a header of (struct hdlc_header), so hard_header_len should be set to sizeof(struct hdlc_header).
