Subject: [PATCH 0/2] forcedeth: recv cache support 

This recv cache is to make NIC work steadily when the system memory is
not enough.

>From long time testing, the NIC worked very well when the system memory
is not enough. And the NIC performance is better from about 920M to
about 940M.

Some simple tests are made:

ip link set forcedeth_nic down/up
modprobe/rmmod forcedeth
ip link set mtu 1500 dev forcedeth_nic
ethtool -G forcedeth_nic tx 512 rx 1024
And other tests, the NIC with the recv cache can work well.

Since the recv cache will reserve 125M memory for NIC, normally this recv
cache is disabled by default.
