VM_IOREMAP is used to access hardware through a mechanism called
I/O mapped memory. Android binder is a IPC machanism which will
not access I/O memory.
Also VM_IOREMAP has alignment requiement which may not needed in
binder.

This fixes warning around a asterisk used in ks_wlan_net.c
for the define statement used for this driver's transmit
queue timeout value as defined by the marco, TX_TIMEOUT.

Check for ethtool_ops structures that are only stored in the ethtool_ops
field of a net_device structure or passed as the second argument to
netdev_set_default_ethtool_ops. These contexts are declared const, so
ethtool_ops structures that have these properties can be declared as const
also.

RX path uses pknd to find the correct device, and we maintain 1:1
port to pknd mapping. However, this is only set for XAUI interfaces
(in the arch code). But it should be set for all interface types.

Hi,
This series implements multiple RX group support that should improve

I'm not using CONFIG_NET_POLL_CONTROLLER either; the problem is in the
normal cvm_oct_napi_poll() path.
