DM36x在2.6.37kernel下网络性能如何？
DM36x的驱动性能数据都可以在下面的wiki网页里找到：

我分别在kernel2.6.18和2.6.37下用iperf做了测试：
2.6.18 下
# ./iperf -c 192.168.1.70 -w 32768 -d -t 60
------------------------------------------------------------Server listening on TCP port 5001TCP window size: 64.0 KByte (WARNING: requested 32.0 KByte)------------------------------------------------------------------------------------------------------------------------Client connecting to 192.168.1.70, TCP port 5001TCP window size: 64.0 KByte (WARNING: requested 32.0 KByte)------------------------------------------------------------[ 5] local 192.168.1.99 port 4578 connected with 192.168.1.70 port 5001[ 4] local 192.168.1.99 port 5001 connected with 192.168.1.70 port 4509[ ID] Interval Transfer Bandwidth[ 5] 0.0-60.0 sec 325 MBytes 45.4 Mbitsc[ 4] 0.0-59.9 sec 353 MBytes 49.4 Mbitsc
而在2.6.37下
./iperf -c 192.168.1.70 -w 32768 -d -t 60------------------------------------------------------------Server listening on TCP port 5001TCP window size: 64.0 KByte (WARNING: requested 32.0 KByte)------------------------------------------------------------------------------------------------------------------------Client connecting to 192.168.1.70, TCP port 5001TCP window size: 64.0 KByte (WARNING: requested 32.0 KByte)------------------------------------------------------------[ 3] local 192.168.1.77 port 55370 connected with 192.168.1.70 port 5001[ 5] local 192.168.1.77 port 5001 connected with 192.168.1.70 port 4624[ ID] Interval Transfer Bandwidth[ 3] 0.0-60.0 sec 248 MBytes 34.6 Mbitsc[ 5] 0.0-60.0 sec 127 MBytes 17.7 Mbitsc
请问2.6.37下的emac驱动是不是有性能问题？
