The hardware queue scheduling is apparently configured with fixed
|
|
priorities, which creates a nasty fairness issue where traffic from one
|
|
CPU can starve traffic from all other CPUs.
|
|
|
|
Work around this issue by forcing all tx packets to go through one CPU,
|
|
until this issue is fixed properly.
