Since we already have a private counter tracking DMA mapping errors, I
would follow what the driver does elsewhere in the transmit path,
especially what bcm_sysport_insert_tsb() does, and just use
dev_consume_skb_any() here.

Are you saying that if the packet drop is accounted is some statistics
we should not inform drop monitor about it? 🤔️
That wasn't my understanding of kfree_skb vs consume_skb..

Yes that's my reasoning here, now given that we have had packet drops on
transmit that took forever to track down, maybe I better retract that
statement and go with v1.

Sounds good, we can apply v1. Would you like to ack/review here?


Yes, now done, thanks!
