From bc356cef8245214321c6b944bb8ebe2e72542387 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Sat, 1 Nov 2014 12:37:03 +0000 Subject: ppp: support adaptive LCP echos Port Debians adaptive LCP echo patch to pppd, make it configurable with UCI and enable it by default. When adaptive LCP echo is enabled, LCP echo requests are only sent if the link is idle, this avoids the common situation where a congested PPP link (e.g. during torrenting) is falsely detected as disconnected because the LCP replies are not received in time. Also bump the copyright year in the Makefile, remove a redundant maintainer entry and fix the shell processing of the keepalive option when the two- value syntax is used.
