[Ankur] I thought of an alternative to implement the above. If the capability 
does not have any *_INTERNAL_PORT_* caps, it will be a SW PMD. Is this correct? 
In that case capability will be used to skip the if checks instead of the pmd specific
name comparison. Please let me know your thoughts on this.
