l2: L2/L3 mode swicth cleanup and l2-patch fix
Cleanup L2/L3 mode switch to not redirect to/from ethernet-input node as it is no longer necessary. L2 patch should use sw_if_index for device feature enable/disable. Type: fix Signed-off-by: John Lo <loj@cisco.com> Change-Id: I0f24161d027b07c188fd1e05276146f94c075710 (cherry picked from commit f415a3b53a51b261d08cc3312c25f250d6bc1bd6)
