[ 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).
