some addresses may be possible. Remove the logic
that tracks whether ARP filter is enabled or not
and give the driver the total number of addresses
instead of the length of the list so it can make

The Nomadik Pinctrl driver requires access to some PRCMU registers
in order to run with full functionality. When Device Tree is
disabled the required PRCMU base address is passed in via platform
data, so in order for Device Tree booting to be as functional, we
need a similar mechanism to fetch it from Device Tree.
The new semantics goes like this: Parse the Device Tree and look
for the PRCMU node using a provided Phandle. Obtain the ioremaped
address from that node. If one was supplied via platform data
over-write it with anything found in Device Tree. Fail if either
the prcm_base can't be found if we're running on anything other
than an STN8815 ASIC.

The AB8500 Pinctrl driver uses PRCMU register addresses to
control Pinctrl related functions. For this to happen, the
Pinctrl driver needs the PRCMU base to work from. We can do
that using standard Open Firmware (of_*) function calls, but
first we need a mechanism to gain access to the PRCMU
device node. We're going to use a Phandle in this case.

When there is heavy transmission traffic in the CPDMA, then Rx descriptors
memory is also utilized as tx desc memory looses all rx descriptors and the
driver stops working then.
This patch adds boundary for tx and rx descriptors in bd ram dividing the
descriptor memory to ensure that during heavy transmission tx doesn't use
rx descriptors.
This patch is already applied to davinci_emac driver, since CPSW and
davici_dmac shares the same CPDMA, moving the boundry seperation from
Davinci EMAC driver to CPDMA driver which was done in the following
commit

net/davinci: do not use all descriptors for tx packets
The driver uses a shared pool for both rx and tx descriptors.
During open it queues fixed number of 128 descriptors for receive
packets. For each received packet it tries to queue another
descriptor. If this fails the descriptor is lost for rx.
The driver has no limitation on tx descriptors to use, so it
can happen during a nmap / ping -f attack that the driver
allocates all descriptors for tx and looses all rx descriptors.
The driver stops working then.
To fix this limit the number of tx descriptors used to half of
the descriptors available, the rx path uses the other half.
Tested on a custom board using nmap / ping -f to the board from
two different hosts.

The lines
if (mlx4_is_mfunc(dev)) {
nreq = 2;
} else {
which hard code the number of requested msi-x vectors under multi-function
mode to two can be removed completely, since the firmware sets num_eqs and
reserved_eqs appropriately Thus, the code line:
nreq = min_t(int, dev->caps.num_eqs - dev->caps.reserved_eqs, nreq);
is by itself sufficient and correct for all cases. Currently, for mfunc
mode num_eqs = 32 and reserved_eqs = 28, hence four vectors will be enabled.
This triples (one vector is used for the async events and commands EQ) the
horse power provided for processing of incoming packets on netdev RSS scheme,
IO initiators/targets commands processing flows, etc.

Commit 5b4c4d3686 "mlx4_en: Allow communication between functions on
same host" introduced a regression under which a bridge acting as vSwitch
whose uplink is an mlx4 Ethernet device become non-operative in native
(non sriov) mode. This happens since broadcast ARP requests sent by VMs
were loopback-ed by the HW and hence the bridge learned VM source MACs
on both the VM and the uplink ports.
The fix is to place the DMAC in the send WQE only under SRIOV/eSwitch
configuration or when the device is in selftest.
