Currently, Synopsys has three series IPs cores. They are
1. 10M/100M/1G (GMAC, QoS)
2. 1G/2.5G/5G/10G (XGMAC)
3. 10G/25G/40G/50G/100G (XLGMAC)
More info: https://www.synopsys.com/designware-ip/interface-ip/ethernet.html
You have successfully merged dwc_eth_qos.c into stmmac. stmmac now fully
supports the 10M/100M/1G series IPs. Personally, I do support Florian's
suggestion not to rename stmmac.
considering to avoid future confusion and make easy maintenance, Following is
my suggestions
1. not to do any rename
2. keep all 10M/100M/1G IPs (GMAC, QoS) development in stmmac.
3. keep all 1G/2.5G/5G/10G IP (XGMAC) development in amd-xgbe.
4. submit a new driver under synopsys/ for the new 10G/25G/40G/50G/100G
(XLGMAC) IP.
Welcome opinions from others.
Thanks,
Jie
