[PATCH v3 3/3] net: emaclite: fix handling for IP packets with specific lengths

From: Samuel Obuch The maximum length is capped similarly to the emaclite_send function. Avoid integer underflow for values of ip->ip_len < 30, the minimum length of an IP packet is 21 bytes. Signed-off-by: Samuel Obuch --- drivers/net/xilinx_emaclite.c | 4 +++- 1 file changed, 3 inse

[PATCH v3 1/3] net: emaclite: enable for more architectures

From: Samuel Obuch Function ioremap_nocache seems to be defined only for MIPS and Microblaze architectures. Therefore, the function call in the emaclite driver causes this driver to be unusable with other architectures, for example RISC-V. Use ioremap function instead of ioremap_nocache

[PATCH v3 2/3] net: emaclite: fix xemaclite_alignedread/write functions

From: Samuel Obuch Use __raw_read* and __raw_write* functions to ensure read/write is passed to the memory-mapped regions, as non-volatile accesses may get optimised out. Signed-off-by: Samuel Obuch --- drivers/net/xilinx_emaclite.c | 9 - 1 file changed, 4 insertions(+), 5 deletions

From: Samuel Obuch Function ioremap_nocache seems to be defined only for mips and microblaze architectures. Therefore, the function call in the emaclite driver causes this driver to be unusable with other architectures, for example riscv. v2: Use ioremap function instead of ioremap_nocache

Re: [PATCH 1/3] net: emaclite: fix broken build

Hi, using linux/io.h and ioremap works well for us, thanks. I will update the patch. S On Mon, Aug 8, 2022 at 9:44 AM Michal Simek wrote: > Hi, > > On 8/8/22 09:35, Michal Simek wrote: > > > > > > On 8/6/22 19:31, Ramon Fried wrote: > >> On Wed, Jul 13, 2

net: emaclite: Fixes, enable driver for other archs

These patches solve a few issues with the driver observed on a RISC-V platform.
