Subject[PATCH v2 0/2] net: arc_emac: fix tx issues
Date
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
