Subject: [PATCH v9 06/14] pkt-line: extract set_packet_header()
Date: Tue, 4 Oct 2016 14:59:39 +0200 [thread overview]
Message-ID: <20161004125947.67104-7-larsxschneider@gmail.com> (raw)
In-Reply-To: <20161004125947.67104-1-larsxschneider@gmail.com>
From: Lars Schneider <larsxschneider@gmail.com>
Extracted set_packet_header() function converts an integer to a 4 byte
hex string. Make this function locally available so that other pkt-line
functions could use it.
