<DIV><FONT face=Arial size=2><SPAN class=248283118-18012009>This patch adds
MSI-X support to MLX4 driver.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=248283118-18012009>To remind, current
driver creates 2 EQs (for commands/events and completions), which both use 1
legacy interrupt.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=248283118-18012009>With this patch
MLX4 requests (in inf file) 18 MSI-X interrupt vectors, spreaded
across processors in round-robin way.</SPAN></FONT></DIV>
<DIV><SPAN class=248283118-18012009><FONT face=Arial size=2>If the platform
doesn't support MSI-X vectors, the driver uses legacy
interrupts.</FONT></SPAN></DIV>

<DIV><SPAN class=248283118-18012009><FONT face=Arial size=2>MSI-X support
required some changes in the card reset mechanism, which is also found in the
patch.</FONT></SPAN></DIV>
