- Reduce code duplication by moving WRB-frags setup into a function. - Do not setup WRB-header before frags are setup, which is unncessary if there's errors while setting up frags. We should only grab an entry for the header, setup the frags and if everything is fine setup the header. - The error cleanup can be moved into a small function.

The WRB header is setup by wrb_fill_hdr() routine. This routine currently gets some of the WRB params as args and figures out rest of the WRB params by looking at various fields in skb (like gso, checksum, vlan-tag etc). All these params could instead be retrieved from the skb into a structure and passed to this routine. This separates wrb_fill_hdr() to only provide chip-specific code to fill the WRB. This also makes it simple to support chips with different WRB formats. Signed-off-by: NSriharsha Basavapatna <sriharsha.basavapatna@emulex.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Andrew Lunn says: ==================== Indirect phy access for mv88e6171 These two patches allow the mv88e6171 driver to access the port phys using indirect addressing. Depending on pin strapping, the switch either uses a single address on the host MDIO bus, requiring the port phys are accessed indirectly, or the switch uses a number of addresses on the host bus and the phys can be directly accessed. The 370RD, the first supported platform to use the 6171 uses multiple addresses, so this indirect mode was not required. However the WRT1900AC has the switch configured to use a single address, and so indirect access is needed. The mv88e6352 already has all the needed code. Refactor it into the shared mv88e6xxx and then use it in the mv88e6171 driver. Tested on the 370RD and WRT1900AC. It would be good if Guenter Roeck could test on his platform to ensure i've not broken anything for the mv88e6352. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When the device is configured to use single chip addressing mode, the phy devices of the port are not accessible on the host MDIO bus. Instead the switch internal MDIO bus must be used.

The mv88e6352 allows access to the port phys via an internal mdio bus which is accessed using registers in the GLOBAL 2 range. The mv88e6171 and probably other devices use the same mechanism.

Commit a7854487: md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write. Causes an RCW cycle to be forced even when the array is degraded. A degraded array cannot support RCW as that requires reading all data blocks, and one may be missing. Forcing an RCW when it is not possible causes a live-lock and the code spins, repeatedly deciding to do something that cannot succeed. So change the condition to only force RCW on non-degraded arrays.

I tried to use these scripts in an ubuntu 14.04 host (gdb 7.7 compiled against python 3.3) but there were several errors. I believe this patch fixes these issues so that the commands now work (I tested lx-symbols, lx-dmesg, lx-lsmod). Main issues that needed to be resolved: * In python 2 iterators have a "next()" method. In python 3 it is __next__() instead (so let's just add both). * In older python versions there was an implicit conversion in object.__format__() (used when an object is in string.format()) where it was converting the object to str first and then calling str's __format__(). This has now been removed so we must explicitly convert to str the objects for which we need to keep this behavior. * In dmesg.py: in python 3 log_buf is now a "memoryview" object which needs to be converted to a string in order to use string methods like "splitlines()". Luckily memoryview exists in python 2.7.6 as well, so we can convert log_buf to memoryview and use the same code in both python 2 and python 3. This version of the patch has now been tested with gdb 7.7 and both python 3.4 and python 2.7.6 (I think asking for at least python 2.7.6 is a reasonable requirement instead of complicating the code with version checks etc).
