I can confirm that the result of the “Supported link modes:” section is identical with the Intel ixgbe-5.19.9 driver:
uname -r
5.10.0-29-amd64

apt install linux-headers-$(uname -r) gcc make
wget https://downloadmirror.intel.com/812532/ixgbe-5.19.9.tar.gz
tar xf ixgbe-5.19.9.tar.gz -C /usr/local/src/
make -j 8

modinfo ./ixgbe.ko
rmmod ixgbe
modprobe dca
insmod ./ixgbe.ko
