From: Bobby Eshleman <[email protected]> Add nk_devmem.py with four tests for TCP devmem through a netkit device:
These tests are just duplicates of the original devmem tests, with some adjusted parameters such as telling ncdevmem to avoid device setup (since it only has access to netkit, not a phys device). Each test uses NetDrvContEnv with primary_rx_redirect=True to set up the BPF redirect program on the primary netkit interface.
