Exact Broadcom B43 driver

This might be a stupid question but here we go. My laptop has a Broadcom wifi card, the exact info being:

    Slot:   06:00.0
    Class:  Network controller [0280]
    Vendor: Broadcom Limited [14e4]
    Device: BCM4311 802.11b/g WLAN [4311]
    SVendor:    Hewlett-Packard Company [103c]
    SDevice:    BCM4311 802.11b/g Wireless LAN Controller [1364]
    Rev:    01

It works with the B43 driver. However, when I open the /lib/firmware/b43 directory there is a long list of files like:

    0g0bsinitvals5.fw lcn1initvals25.fw n0bsinitvals25.fw ucode14.fw
    a0g0bsinitvals9.fw lcn1initvals26.fw n0initvals11.fw ucode15.fw
    a0g0initvals5.fw lcn2bsinitvals24.fw n0initvals16.fw ucode16_lp.fw
    a0g0initvals9.fw lcn2bsinitvals25.fw n0initvals17.fw ucode16_mimo.fw
    a0g1bsinitvals13.fw lcn2bsinitvals26.fw n0initvals22.fw ucode16_sslpn.fw
    a0g1bsinitvals5.fw lcn2initvals24.fw n0initvals24.fw ucode16_sslpn_nobt.fw

I just posted a few lines, repeat it's a long list.

My question is twofold. A) What do all these files mean? B) Do I need them all or, knowing exactly the driver on my machine as listed above, is there a way to identify those few files I truly need and erase all the others?
