net: dc2114x: remove the pass all multicast flag in operation mode settings 2024-10-27T16:15:29+00:00 Hanyuan Zhao hanyuan-z@qq.com 2024-08-09T08:57:01+00:00 ba30f462a2678c29b5243f7305b5502240c978f8 Remove the OMR_PM flag and choose 16 perfect filtering mode since in modern networks there're plenty of multicasts and set ORM_PM flag will increase the dc2114x's workload and ask the U-Boot to handle packets not related to itself. And most of the time, U-Boot does not need this feature. Signed-off-by: Hanyuan Zhao <zhaohy22@mails.tsinghua.edu.cn>

net: dc2114x: allow users to decide how to tx packets according to IP core 2024-10-27T16:15:29+00:00 Hanyuan Zhao hanyuan-z@qq.com 2024-08-09T08:57:00+00:00 c303f4a0dd7a6fba0a3103c1f8f490929ae5b578 Some IP cores of dc2114x or its variants do not comply so well with the behaviors described by the official document. Originally this driver uses only one tx descriptor and organizes it as a ring buffer, which would lead to a problem that one packet would be sent twice. This commit adds support to prevent this bug if you are using IP cores with this issue, by using multiple tx descriptors and organizing them as a real well-defined ring buffer.

net: dc2114x: add support for CPUs that have cache between the memory and the card 2024-10-27T16:15:29+00:00 Hanyuan Zhao hanyuan-z@qq.com 2024-08-09T08:56:57+00:00 23edc8f6a6a1f08c1c0e84bd232dedad057d2c6d This commit adds support for the MIPS and LoongArch CPUs, which would use cache after they jump into U-Boot. This commit requests the CPU to return the addresses in uncached windows and flushes the cache in need, to make sure the memory between the CPU and the network card is in consistency.
