-Subject: [PATCH 33/34] b43: add workaround for b43 on pcie bus of bcm4716.
-
-bcm4716 (which includes 4717 & 4718), plus 4706 on PCIe can reorder
-transactions. As a fix, a read after write is performed on certain
-places in the code. Older chips and the newer 5357 family don't require
-this fix.
-This code is based on the brcmsmac driver.
