[packman] broadcom-wl driver vs. Linux kernel v5.10

[Ilgaz Öcal]

Hello

I have a broadcom 43142 here and would be happy to test. Unfortunately 
same issue (kernel change) breaks the realtek 8821cu which I rely on 
too. See https://github.com/brektrou/rtl8821CU/issues/100#issue-741264469

Have a nice day and thanks for caring

NIC (this will likely break on 5.10 too)
