Porting a driver from RELENG_6 to RELENG_6_2

[Rajkumar S]

Hi,

I have a Marvell Yukon 88E8050 Gigabit Ethernet which came with my
motherboard. When looking for it's driver I found that RELENG_6
supports it, and the driver is located at sys/dev/msk/ But I am using
RELENG_6_2.

Is it advisable to take this driver from RELENG_6 to RELENG_6_2? Is
there some established method to get a diff of this driver alone and
apply it to RELENG_6_2?

regards,

raj
