2016-11-16alx: prepare resource allocation for multi queue supportTobias Regnery1-52/+97
Allocate, initialise and free alx_tx_queue structs based on the number of alx_napi structures. Also increase the size of the descriptor memory based on the number of tx queues in use. Based on the downstream driver at github.com/qca/alx Signed-off-by: Tobias Regnery <tobias.regnery@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-16alx: prepare interrupt functions for multiple queuesTobias Regnery1-27/+105
Extend the interrupt bringup code and the interrupt handler for msi-x interrupts in order to handle multiple queues. We must change the poll function because with multiple queues it is possible that an alx_napi structure has only a tx or only a rx queue pointer.

2016-11-16alx: switch to per queue data structuresTobias Regnery2-95/+93
Remove the tx and rx queue structures from the alx_priv structure and switch everything over to the queue pointers in the alx_napi structure.

2016-11-16alx: add ability to allocate and free alx_napi structuresTobias Regnery1-21/+78
Add new functions to allocate and free the alx_napi structures and use them in __alx_open and __alx_stop. We only allocate one of these structures for now, as the rest of the driver is not yet ready for multiple queues. We switch over the setup of the interrupt mask and the call to netif_napi_add to the new function because we must adjust these later on a per queue basis.

2016-11-16alx: refactor descriptor allocationTobias Regnery1-44/+53
Split the allocation of descriptor memory and the buffer allocation into a tx and rx function. This is in preparation for multiple queues where we need to iterate over the new functions. While at it drop the unneeded casting on the rx side. Signed-off-by: Tobias Regnery <tobias.regnery@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-11-16net: ethernet: sun4i-emac: Read rxhdr in CPU byte-orderMichael Weiser1-2/+1
The EMAC EMAC_RX_IO_DATA_REG data register is dual-purpose: On one hand it is used to move actual packet data off the wire. This will be in wire-format and accepted as such by higher layers such as IP. Therefore it is correctly read as-is (i.e. raw) using readsl. On the other hand it provides metadata about incoming transfers to the driver such as length and checksum validation status. This data is little-endian, always and it is interpreted by the driver. Therefore it needs to be swapped to CPU endianness to make sense to the driver. This is already done for the "receive header" but not rxhdr. Read rxhdr using readl in order for sun4i-emac to work correctly when running a big-endian kernel.

2016-11-16net: ethernet: stmmac: change dma descriptors to __le32Michael Weiser8-181/+195
The stmmac driver does not take into account the processor may be big endian when writing the DMA descriptors. This causes the ethernet interface not to be initialised correctly when running a big-endian kernel. Change the descriptors for DMA to use __le32 and ensure they are suitably swapped before writing.
