struct sha256_state compile error with Ubuntu 20.10

[rolandbreedveld]

Cant compile this with Ubuntu 20.20:

dkms build -m rtl88x2bu -v ${VER}

Kernel preparation unnecessary for this kernel. Skipping...

I see, cilynx is not in a hurry to propose a fix, not at all.

Hey I've got it working using rincat's driver fork

sudo git clone "https://github.com/RinCat/RTL88x2BU-Linux-Driver.git" /usr/src/rtl88x2bu-git
sudo sed -i 's/PACKAGE_VERSION="@PKGVER@"/PACKAGE_VERSION="git"/g' /usr/src/rtl88x2bu-git/dkms.conf
sudo dkms add -m rtl88x2bu -v git
sudo dkms autoinstall

$ uname -r
5.10.0

However, it does not see 5G networks, I am unable to connect to my AP.
