ar71xx: rb91x: fix pll_1000 value for eth0 to avoid packet loss
When the RB91x device uses a GbE link the connection suffers from packet loss: root@OpenWrt:/# ping 192.168.1.254 -s 65507 -c 20 -q PING 192.168.1.254 (192.168.1.254): 65507 data bytes --- 192.168.1.254 ping statistics --- 20 packets transmitted, 9 packets received, 55% packet loss round-trip min/avg/max = 4.570/4.815/4.999 ms Using a different PLL value fixes the issue. root@OpenWrt:/# ping 192.168.1.254 -s 65507 -c 100 -q PING 192.168.1.254 (192.168.1.254): 65507 data bytes --- 192.168.1.254 ping statistics --- 100 packets transmitted, 100 packets received, 0% packet loss round-trip min/avg/max = 4.449/5.413/13.870 ms Signed-off-by: Gabor Juhos <juhosg@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@39642 3c298f89-4303-0410-b956-a3cf2f4a3e73
