From e28634d6b229dec216596298c765c203d6b6fa4c Mon Sep 17 00:00:00 2001 From: Matvejchikov Ilya Date: Tue, 12 Jul 2011 21:46:17 +0000 Subject: slip: fix MTU comparation operation when reallocating buffers In sl_realloc_bufs() there is no reason to check if the requested MTU greater than or equal to the current MTU value as this function called only when requested MTU not equals to the current value. So, the ">=" operation can be safely replaced with the ">". Signed-off-by: Matvejchikov Ilya Signed-off-by: David S.
