TX_E_PRIO_CHANGE event is never sent for bna_tx so it doesn't need to be

The bna_rx_config struct member paused can be removed as it is never
written and as it cannot have non-zero value the bna_rxf struct member
flags also cannot have BNA_RXF_F_PAUSED value and is always zero.
So the flags member can be removed as well as bna_rxf_flags enum and
the code-paths that needs to have non-zero bna_rxf->flags.
This clean-up makes bna_rxf_sm_paused state unsed and can be also removed.

Parameters of all ether_addr_copy instances were checked for proper
alignment. Alignment of bnad_bcast_addr is forced to 2 as the implicit
alignment is 1.
I have also renamed address parameter of bnad_set_mac_address() to addr.
The name mac_addr was a little bit confusing as the real parameter is
struct sockaddr *.

bnad_set_mac_address() (thx joe@perches.com)

Each transport object, namely TIR and TIS, must have a transport domain
number (TDN) identifier.
The driver wrongly assumed that it is OK to use TDN=0 without explicit
TDN allocation from the device.
The TDN will also be used for isolating different processes once user
mode Ethernet will be supported.

When NETIF_F_SG is set, each send WQE may have a different size since
each skb can have different number of fragments as of LSO header etc.
This implies that a given WQE may wrap around the send queue, i.e begin
at its end and continue at its start. While it is legal by the device spec,
we preferred a solution that avoids it - when building of current WQE is
done, if the next WQE may wrap around the send queue, fill the send queue
with NOPs WQEs till its end, so that the next WQE will begin at send queue
start.
NOP WQE for itself cannot wrap around the send queue since it is of
minimal size - 64 bytes, and all send WQEs are a multiple of that size.

Some NFC controller supports UART as host interface.
As with SPI, a lot of code can be shared between vendor
drivers. This patch add the generic support of UART and
provides some extension API for vendor specific needs.
This code is strongly inspired by the Bluetooth HCI ldisc
implementation. NCI UART vendor drivers will have to register
themselves to this layer via nci_uart_register.
Underlying tty will have to be configured from user land

When the DEBUG preprocessor macro is defined the ps3_gelic_net driver build
fails due to an undeclared routine gelic_descr_get_status(). This problem
was introduced during the code cleanup of commit
6b0c21cede22be1f68f0a632c0ca38008ce1abe7 (net: Fix p3_gelic_net sparse warnings),
which re-arranged the ordering of some of the gelic routines.
This change just moves the gelic_descr_get_status() routine up in the
ps3_gelic_net.c source file. There is no functional change.

net: broadcom MDIO support for broken turn-around
These two patches update the GENET and UniMAC MDIO controllers to deal with
PHYs that are known to have a broken turn-around bug (e.g: BCM53125 and others)
This utilizes the infrastructure that code recently added to do that in 'net-next'.
Note that the changes look nearly identical and I will try to address the MDIO
code duplication between GENET and UniMAC in a future patch series.
Changes in v2:
- remove brcmphy.h include in mdio-bcm-unimac.c
- use the same comment as with GENET's MDIO read function

Some Ethernet PHYs/switches such as Broadcom's BCM53125 have a hardware bug
which makes them not release the MDIO line during turn-around time. This gets
flagged by the UniMAC MDIO controller as a read failure, and we fail the read
transaction.
Check the MDIO bus phy_ignore_ta_mask bitmask for the PHY we are reading
from and if it is listed in this bitmask, ignore the read failure and
proceed with returning the data we read out of the controller.
