* Description:
* Recognize the interrupt content by reading the interrupt

* Arguments:
* [in] Adapter -
* The adapter context.
* [in] pContent -
* Under PCI interface, this field is ignord.
* Under USB interface, the content is the interrupt
* content pointer.
* Under SDIO interface, this is the interrupt type which
* is Local interrupt or system interrupt.
* [in] ContentLen -
* The length in byte of pContent.
* Return:
* If any interrupt matches the mask (IMR), return true, and
* return false otherwise.
