Usually the kernel will probe the device and load the appropriate firmware the 
device needs.  The output of dmesg will show if loading the firmware was 
successful, or complain if different firmware was needed and not found in your 
"/lib/firmware/" or whatever you have set up in your kernel as the directory 
for firmware blobs.

Have a look in:

# Generic Driver Options

and then:

CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FW_LOADER=y
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="Put your firmware files in here, space separated"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware/"

I don't have your NIC to know the specifics, but the above ought to work.
