Subject: [PATCH net-next v2 2/4] net: systemport: Add netconsole support
Implement a poll controller for netconsole which invokes the RX
interrupt handler to poll for incoming packets, and cleans up all TX
queues by invoking the TX interrupt handler.
Signed-off-by: Florian Fainelli <f.fainelli@...il.com>
---
Changes in v2:
- properly pair the interrupt handler calls with disable/enable_irq
- remove the call to bcm_sysport_tx_reclaim, handler does this
