Subject: [PATCH V1 net 4/8] net: ena: fix incorrect test of supported hash function
Date: Wed, 1 May 2019 16:47:06 +0300 [thread overview]
Message-ID: <20190501134710.8938-5-sameehj@amazon.com> (raw)
In-Reply-To: <20190501134710.8938-1-sameehj@amazon.com>
From: Sameeh Jubran <sameehj@amazon.com>
ena_com_set_hash_function() tests if a hash function is supported
by the device before setting it.
The test returns the opposite result than needed.
Reverse the condition to return the correct value.
Also use the BIT macro instead of inline shift.
Fixes: 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
