From c5c2523893747f88a83376abad310c8ad13f7197 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 9 Apr 2007 11:47:18 -0700 Subject: [XFRM]: Optimize MTU calculation Replace the probing based MTU estimation, which usually takes 2-3 iterations to find a fitting value and may underestimate the MTU, by an exact calculation. Also fix underestimation of the XFRM trailer_len, which causes unnecessary reallocations. Signed-off-by: Patrick McHardy Signed-off-by: David S.
