| Subject: drivers/net/wan/hdlc_cisco: Add hard_header_len |
| |
| From: Xie He <xie.he.0141@gmail.com> |
| |
| [ Upstream commit 1a545ebe380bf4c1433e3c136e35a77764fda5ad ] |
| |
| 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). |
