ixgbe(4): Fix enabling/disabling and reconfiguration of queues

Authored by on Jul 1 2019, 5:21 PM.


  • Wrong order of casting and bit shift caused that enabling and disabling queues didn't work properly for queues number larger than 32. Use literals with right suffix instead.
  • TX ring tail address was not updated during reinitiailzation of TX structures. It could block sending traffic.
  • Also remove unused variables 'eims' and 'active_queues'.
Test Plan

Respectfully requesting our Validation Team to perform a test pass before committing.
