Drivers binaries have been renamed during 20.11.
See a20b2c01a7a1 ("build: standardize component names and defines").

In your dpdk 20.11 build, look for rte_net_e1000.a.

(Note that I suspect that this 3rd party application will have more
issues than just linking. I suggest you look at the API/ABI changes
sections in the v20.11 release notes)
