[PATCH 4.9 19/31] qed: Fix mask for physical address in ILT entry

2018-06-12 Thread Greg Kroah-Hartman 
4.9-stable review patch.  If anyone has any objections, please let me know.

From: Shahed Shaikh 

[ Upstream commit fdd13dd350dda1826579eb5c333d76b14513b812 ]

ILT entry requires 12 bit right shifted physical address.
Existing mask for ILT entry of physical address i.e.
ILT_ENTRY_PHY_ADDR_MASK is not sufficient to handle 64bit
address because upper 8 bits of 64 bit address were getting
masked which resulted in completer abort error on
PCIe bus due to invalid address.

Fix that mask to handle 64bit physical address.
