net-next commit 6d91147d18 ("batman-adv: Remove uses of return value
of seq_printf") incorrectly changed the overflow occurred return from
-1 to 1. Change it back so that the test of batadv_write_buffer_text's
return value in batadv_gw_client_seq_print_text works properly.

Although it is clear that textsearch state is intentionally passed to
skb_find_text() as uninitialized argument, it was never used by the
callers. Therefore, we can simplify skb_find_text() by making it
local variable.

- 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 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.

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.
