Strix Z270F Gaming主板用的是I-219V网卡，装上ubuntu 16.04后发现没有网卡驱动。经过测试，用如下方法能解决问题：
- 下载驱动e1000e （3.3.5.3）

(https://downloadcenter.intel.com/download/15817/Intel-Network-Adapter-Driver-for-PCI-E-Gigabit-Network-Connections-under-Linux-?product=71307)

• 修改src/nvm.c: 563行,将e1000e_validate_nvm_checksum_generic函数改成直接返回0.

s32 e1000e_validate_nvm_checksum_generic(struct e1000_hw *hw)
{
#if 0
    s32 ret_val;
    u16 checksum = 0;
    u16 i,nvm_data;

    for (i = 0; i < (NVM_CHECKSUM_REG + 1); i++) {
        ret_val = e1000_read_nvm(hw,i,1,&nvm_data);
        if (ret_val) {
            e_dbg("NVM Read Error\n");
            return ret_val;
        }
        checksum += nvm_data;
    }

    if (checksum != (u16)NVM_SUM) {
        e_dbg("NVM Checksum Invalid\n");
        return -E1000_ERR_NVM;
    }
#endif
    return 0;
}

• Make and install

$ make
$ sudo make install
$ sudo modprobe e1000e
