net: systemport: Decouple flow control from __bcm_sysport_tx_reclaim
[ Upstream commit 148d3d021cf9724fcf189ce4e525a094bbf5ce89 ]
The __bcm_sysport_tx_reclaim() function is used to reclaim transmit
resources in different places within the driver. Most of them should
not affect the state of the transit flow control.
Introduce bcm_sysport_tx_clean() which cleans the ring, but does not
re-enable flow control towards the networking stack, and make
bcm_sysport_tx_reclaim() do the actual transmit queue flow control.
