From 10b9b98e41ba248a899f6175ce96ee91431b6194 Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Tue, 20 Mar 2012 12:55:09 +0300 Subject: CIFS: Respect negotiated MaxMpxCount Some servers sets this value less than 50 that was hardcoded and we lost the connection if when we exceed this limit. Fix this by respecting this value - not sending more than the server allows.
