      skb: Add inline helper for getting the skb end offset from head · ec47ea82
      由 Alexander Duyck 提交于 
      With the recent changes for how we compute the skb truesize it occurs to me
we are probably going to have a lot of calls to skb_end_pointer -
skb->head.  Instead of running all over the place doing that it would make
more sense to just make it a separate inline skb_end_offset(skb) that way
we can return the correct value without having gcc having to do all the
optimization to cancel out skb->head - skb->head.

      cdc_ether: Ignore bogus union descriptor for RNDIS devices · 6eddcb4c
      由 Bjørn Mork 提交于 
      Some RNDIS devices include a bogus CDC Union descriptor pointing
to non-existing interfaces.  The RNDIS code is already prepared
to handle devices without a CDC Union descriptor by hardwiring
the driver to use interfaces 0 and 1, which is correct for the
devices with the bogus descriptor as well. So we can reuse the
existing workaround.

      bnx2x: bug fix when loading after SAN boot · 24f06716
      由 Ariel Elior 提交于 
      This is a bug fix for an "interface fails to load" issue.
The issue occurs when bnx2x driver loads after UNDI driver was previously
loaded over the chip. In such a scenario the UNDI driver is loaded and operates
in the pre-boot kernel, within its own specific host memory address range.
When the pre-boot stage is complete, the real kernel is loaded, in a new and
distinct host memory address range. The transition from pre-boot stage to boot
is asynchronous from UNDI point of view.

A race condition occurs when UNDI driver triggers a DMAE transaction to valid
host addresses in the pre-boot stage, when control is diverted to the real
kernel. This results in access to illegal addresses by our HW as the addresses
which were valid in the preboot stage are no longer considered valid.
Specifically, the 'was_error' bit in the pci glue of our device is set. This
causes all following pci transactions from chip to host to timeout (in
accordance to the pci spec).
