INTEL I226 网卡关机后WOL不能启动

最近尝试换了一款新的48口2.5G交换机，由于交换机电口只能支持最低100m速率（100/1000/2500mbps），这就导致了INTEL I226网卡在LINUX环境下的唤醒问题。查询了相关文档，intel方面表示由于遵守能源之星要求，导致网卡在D3电源模式下禁用了100m速率，只支持10m速率，而新款交换机最低只能支持100m速度，在unraid休眠后网卡接口就会down掉。好像目前只限于linux环境，在win环境下没这个限制。请问如何自己编译一下intel i226的驱动使其在D3模式支持100m网络？

My request for Premier Support was declined..

 

Meanwhile, not very happy with Intel, was looking for some clues in FreeBSD kernel sources and found this:

 

#define IGC_I225_PHPM_DIS_100_D3 0x0200 /* Disable 100M in D3 */

 

WOL problem is solved by clearing this bit in PHY power management register.
