Hi Folks, The current implementation of fcoe-utils is highly dependent on netlink sockets created on network interfaces for receiving netlink events and fc events. We have a new multi PCI function hardware architecture which may not expose L2 interface for storage enabled PCI functions. Due to this network socket dependency we will not be able to use current implementation of fcoe-utils. What we would like to do is add two library functions to libfcoe to be able to initiate a FIP VLAN request and parse the results to inform the LLD of the VLAN via a callback.
More specifically, we would like to add a new exported function to libfcoe, fcoe_send_vlan_req() which would form the FIP frame and send it to the LLD using the fcoe_ctlr->send() callback. Then in fcoe_ctlr_recv(), we would add an additional check for the op FIP_OP_VLAN. If this check is true we would call another new function, fcoe_process_vlan_resp(), where we would extract the VLAN ID. We would also like to add a function callback to the fcoe_ctlr struct, update_vlan(uint16_t vlan), which a LLD could add a handler for to get notification of the VLAN from the FIP VLAN request. Moving this functionality into libfcoe would enable other low level drivers to take advantage of this functionality as well. Note that the implementation of fcoe_send_vlan_req() would be based on fnic_fcoe_send_vlan_req() and fcoe_process_vlan_resp() would be based on fnic_fcoe_process_vlan_resp(). We wanted to get community feedback on this before heading in this direction.
