  netdev-linux: correct unit of burst parameter

Correct calculation of burst parameter used when configuring TC policer
action for ingress port-based policing in the case where TC offload is in
use. This now matches the value calculated for the case where TC offload is
not in use.

The division by 8 is to convert from bits to bytes.
Its unclear why 64 was previously used.

    M tests/system-offloads-traffic.at

  Log Message:
  -----------
  Add test cases for ingress_policing parameters

tests/ovs-vsctl.at: Add ingress_policing test in ovs-vsctl unit test
tests/system-offloads-traffic.at: Check ingress_policing with offloads enabled and disabled

Exercise OVS setting of ingress_policing parameters using ovs-vsctl and verify that the correct values are stored on OVSDB.
Verify the ingress_policing parameters with tc command. Also check offload and non-offload in tc software datapath based on tc filter type (matchall and basic).

Example invocation:
make check TESTSUITEFLAGS='-k ingress_policing'
make check-offloads TESTSUITEFLAGS='-k ingress_policing'
