Replacing the built in Relatek driver on freeBSD10.3 or 11?

[Doboy]

Is there anyone that can help me update the built in Re driver in freebsd 10.3(pfsense 2.3) or 11(pfsense 2.4)? I ask because it woudl solve my watchdog timeout issue i have been having when my WAN NIC is saturated (> 100Mbps) as posted here on the freeBSD forum : https://forums.freebsd.org/threads/55861/

Problem is i am piss poor at linux, freeBSD, Unix.. you name it that's not windows :)

I have never compiled a lick.

or if anyone can point me in the right direction to accomplish this myself? Do i have to compile the code on the Zotac Box I am using with the realtek card? or can i compile it in a more powerful VM then export the compiled driver?

Is there anyway maybe the dev team can incorporate the latest drives into a build? i know its not a priority but i am sure it woudl solve a lot of users realtek NIC issues.

thanks for taking the time.
