* Allow setting of adaptive coalescing setting for all types of interrupt.
* In msi & legacy intr, we use single interrupt for rx & tx. In this case
tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs.
Do not display tx_coal values for msi/intx. And do not allow user to set
this as well.
* Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings.
For other values, driver does not return error. So ethtool succeeds for
unsupported values. Introduce enic_coalesce_valid() function to validate
the coalescing values.
* If user requests for coalesce value greater than what adaptor supports,
driver uses the max value. We should at least log this.
