Hi,
the patches below solve some issues found in the tx ring reclaim strategy currently implemented in the arc_emac driver.
Without these patches a simple outgoing UDP flow blocks almost immediately with the socket send buffer full, until some new rx packets trigger a clean of the tx ring.
Everything seems to work fine on a Radxa Rock with this fix applied.
Changes since v1: - reworded commit messages
Beniamino Galvani (2): net: arc_emac: enable tx interrupts net: arc_emac: prevent reuse of unreclaimed tx descriptors
