I did not overload issue_cmd(), instead I changed the function signature. 

-u32
-qlcnic_issue_cmd(struct qlcnic_adapter *adapter,
-       u32 pci_fn, u32 version, u32 arg1, u32 arg2, u32 arg3, u32 cmd,
-               u32 *rd_args[3])
+void
+qlcnic_issue_cmd(struct qlcnic_adapter *adapter, struct qlcnic_cmd_args *cmd)

Instead of having a long list of arguments, I put them into a struct and passed it around.
