Subject: [dpdk-dev] [PATCH v3 06/19] bus/fslmc: fix parse method for bus devices
Date: Fri, 11 Jan 2019 12:24:23 +0000
Message-ID: <20190111122305.7133-7-shreyansh.jain@nxp.com> (raw)
In-Reply-To: <20190111122305.7133-1-shreyansh.jain@nxp.com>

Current code expects that bus->parse() would get a string containing
the name of the bus. That is incorrect. bus->parse() is expected
to have strings like:
  dpni.1,key=val
  dpio.2,key=val

when user passed:
  -b fslmc:dpni.1,key=val

This commit fixes this behavior.

Fixes: 50245be05d1a ("bus/fslmc: support device blacklisting")
Cc: stable@dpdk.org
