RTL 8111G

[BERTRAND Joël]

	Hello,

	I have installed some months ago a diskless terminal running FreeBSD 
10.x. This workstation contains a MSI H97I AC motherboard and sadly a 
"Realtek® 8111G Gigabit LAN controller".

	With re driver provided by official FreeBSD 10.x kernel, network 
adapter can stop and, as this system is diskless, kernel crashes. I want 
to upgrade this system to FreeBSD 11.x as I have to use wifi adapter 
(Intel Wireless 7260) that is not supported by 10.x.

	I have downloaded the last driver from Realtek (rtl_bsd_drv_v192) and 
I'm unable to build it. Compilation aborts with :

	Does anyone successfully use this RTL 8111G adapter with in-kernel 
driver ? I have seen that some modifications have been done between 10.X 
and 11 but I'm not sure that they fix bugs I have seen with 10.x.

	Best regards,
