Subject: [PATCH v2 0/2] net: arc_emac: fix tx issues
Date: Wed, 10 Sep 2014 22:50:01 +0200 [thread overview]
Message-ID: <1410382203-10395-1-git-send-email-b.galvani@gmail.com> (raw)
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
