From: Kumar Sanghvi Date: Sat, 10 Mar 2018 22:48:19 +0000 (+0530) Subject: net/cxgbe: add skeleton VF driver X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=011ebc236ddc;p=dpdk.git net/cxgbe: add skeleton VF driver Add minimal VF driver. Declare functions common to both PF and VF functionality in separate header file and import the header file.
