0399eca800 ath10k: cleanup ath10k_pci_wait_for_target_init()
ath10k_pci_wait_for_target_init() did really follow the style used elsewhere in
ath10k. Use ath10k_pci_read/write() wrappers, simplify the while loop and
improve warning messages.

be6546fcc2 ath10k: unify warning messages in mac.c
Currently there are different styles used for warning messages, unify them to
look similar. The style basically is:

1) start with a verb (if possible)

2) lower case letters

3) use plain english as much as possible

ebe5e3c642 net: bcmgenet: set RBUF_SKIP_FCS based on UniMAC CRC forwarding
When the UniMAC block is configured to forward the CRC as part of the
Ethernet frame (priv->crc_fwd_en, set by default), enabling the hardware
RX checksum block unveiled that the dma_rxchk_bit was never set in the
per-packet status bits (dma_flag in bcmgenet_desc_rx). This would make
the chksum_ok variable to be never set to 1, and the networking stack
would have to compute the packet checksums, which takes a substantial
amount of time.

In order for the RXCHK block to properly compute the packet checksum in
hardware, we also need to set the RBUF_SKIP_FCS bit accordingly.

14a0d635d1 usbnet: include wait queue head in device structure
This fixes a race which happens by freeing an object on the stack.
Quoting Julius:
> The issue is
> that it calls usbnet_terminate_urbs() before that, which temporarily
> installs a waitqueue in dev->wait in order to be able to wait on the
> tasklet to run and finish up some queues. The waiting itself looks

> wake_up() call in usbnet_bh().

The fix is to just not allocate the data structure on the stack.
As dev->wait is abused as a flag it also takes a runtime PM change
to fix this bug.
