-Subject: [PATCH] bcm63xx_enet: fix napi poll return value
-
-Commit d75b1ade567ffab ("net: less interrupt masking in NAPI") changed
-the way how napi treated a returnvalue < budget, which causes hangs when
-there there was tx_work_done, but rx_work_done is less than budget.
-
-To fix this, return budget instead of rx_done to ensure repolling.
