hi

The intention of this series is to fully enable hard irqs deferral feature
(hrtimers based HW IRQ coalescing) from Eric Dumazet [1] for TI K3 CPSW driver
by using napi_complete_done() in TX completion path, so the combination of
parameters (/sys/class/net/ethX/):
 napi_defer_hard_irqs 
 gro_flush_timeout
can be used for hard irqs deferral.

The Patch 1 is required before enabling hard irqs deferral feature to avoid
"Unbalanced enable" issue if gro_flush_timeout is configured while
(napi_defer_hard_irqs == 0).

It's a bit sad that it can not be configured per RX/TX separately.
