Introduces a module parameter to decide whether the physical
port link state is propagated to the network stack or not.
It makes sense not to take the physical port state into account
on machines with more logical partitions that communicate
with each other. This is always possible no matter what the physical
port state is. Thus eHEA can be considered as a switch there.

net_poll support for eHEA added

The driver didn't allow an interface's MAC address to be modified if the
respective interface wasn't setup - a failing Hcall was the result. Thus
bonding wasn't usable. The fix moves the failing Hcall which was registering
a MAC address for the reception of BC packets in firmware from the port up
and down functions to the port resources setup functions. Additionally the
missing update of the last_rx member of the netdev structure was added.

This patch adds support for DLPAR memory add to the eHEA driver. To detect
whether memory was added the driver uses its own memory mapping table and
checks for kernel addresses whether they're located in already known memory
sections. If not the function ehea_rereg_mrs() is triggered which performs
a rebuild of the mapping table and a re-registration of the global memory
region.

This patch introduces a capability flag that is used by the DLPAR userspace

Hi Jeff,

sorry to bother you again. We figured out that the readq function we
included in the eHEA patch we sent yesterday to access eHEA registers
is defined as little endian on POWER. This collides with our adapter.
We talked to some PPC people who told us there is a discussion going
on about new access functions. We were told to use __raw_readq /
__raw_writeq for now.

This patch fixes this bug found by our internal tests today.
Please apply this small patch on the latest patch we sent you yesterday.
If it is easier for you I can also give you the entire eHEA patch again.

sorry and thanks a lot,
Jan-Bernd

Hi Jeff,

I fixed the __iomem issue and tested the driver with sparse. Looks good so far.
Thanks for your effort.
