From eebb02b1f03b3722d678bfcb560f3b26661ab0d2 Mon Sep 17 00:00:00 2001 From: Shreyas Bhatewara Date: Thu, 7 Jul 2011 00:25:52 -0700 Subject: [PATCH] vmxnet3: round down # of queues to power of two vmxnet3 device supports only power-of-two number of queues. The driver therefore needs to check this and rounds down the number of queues to the nearest power of two.
