From: Harish Patil Date: Wed, 19 Oct 2016 04:11:22 +0000 (-0700) Subject: net/qede/base: change signature of MCP command X-Git-Tag: spdx-start~5458 X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=ffdd0599173b4a00b98c11fb9ebcaaea76fc3abf net/qede/base: change signature of MCP command Change ecore_mcp_cmd_and_union() to accept pointer to a structure rather than accepting multiple arguments. A new struct ecore_mcp_mb_params is added for that purpose. Also make this function static. This change is mostly keeping in mind the future requests which needs additional arguments.
