2020-03-17net: stmmac: Add support for Enterprise MAC versionJose Abreu1-0/+1
Adds the support for Enterprise MAC IP version which is very similar to XGMAC. It's so similar that we just need to check the device id and add new speeds definitions and some minor callbacks. Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-10-06net: stmmac: Fallback to VLAN Perfect filtering if HASH is not availableJose Abreu1-1/+1
If VLAN Hash Filtering is not available we can fallback to perfect filtering instead. Let's implement this in XGMAC and GMAC cores and let the user use this filter. VLAN VID=0 always passes filter so we check if more than 2 VLANs are created and return proper error code if so because perfect filtering only supports 1 VID at a time.

Commit a993db88d17d ("net: stmmac: Enable support for > 32 Bits addressing in XGMAC"), introduced support for > 32 bits addressing in XGMAC but the conversion of descriptors to dma_addr_t was left out. As some devices assing coherent memory in regions > 32 bits we need to set lower and upper value of descriptors address when initializing DMA channels.

We always program the maximum DMA buffer size into the receive descriptor, although the allocated size may be less. E.g. with the default MTU size we allocate only 1536 bytes.

2018-05-10net: stmmac: Add support for U32 TC filter using Flexible RX ParserJose Abreu1-2/+23
This adds support for U32 filter by using an HW only feature called Flexible RX Parser. This allow us to match any given packet field with a pattern and accept/reject or even route the packet to a specific DMA channel. Right now we only support acception or rejection of frame and we only support simple rules. Though, the Parser has the flexibility of jumping to specific rules as an if condition so complex rules can be established. This is only supported in GMAC5.10+. The following commands can be used to test this code: 1) Setup an ingress qdisk: # tc qdisc add dev eth0 handle ffff: ingress 2) Setup a filter (e.g. filter by IP): # tc filter add dev eth0 parent ffff: protocol ip u32 match ip \ src 192.168.0.3 skip_sw action drop In every tests performed we always used the "skip_sw" flag to make sure only the RX Parser was involved.
