Subject: [PATCH 0/2] Fix two bugs of switchtec module

Hi, Everyone,

This patch series fix two bugs of switchtec module.

The first is introduced by device spec definition issue: the maximum
supported PCIe function number by hardware should be 255 instead of 
the false number of 48. Rectify it in driver and for backward 
compatible, a new ioctl and corresponding data structure are created,
while keep the deprecated one.

The second is MRPC event unintentionally masked at corner case.
Fix this bug by skipping the mask operation for MRPC event in event ISR
like what we already do for LINK event.

Regard,
Wesley
