Message-Id: <20150328055050.0CBDB220209@puck.mtv.corp.google.com>
Date: Fri, 27 Mar 2015 22:50:50 -0700 (PDT)
From: Petri Gynther <pgynther@...gle.com>
To: netdev@...r.kernel.org
Cc: davem@...emloft.net, f.fainelli@...il.com, jaedon.shin@...il.com
Subject: [PATCH net-next 1/3] net: bcmgenet: add UMAC_IRQ_RXDMA_DONE and UMAC_IRQ_TXDMA_DONE
Add #define for UMAC_IRQ_RXDMA_DONE and UMAC_IRQ_TXDMA_DONE in order
to simplify the code that handles Rx and Tx default queue interrupts.
