[edk2-devel] [PATCH] RedfishPkg/RedfishDiscoverDxe: fix netmask check issue
Posted by Nickle Wang via groups.io 9 months, 1 week ago
- Add NTOHL() for coverting IP address from EFI_IPv4_ADDRESS to
IP4_ADDR so that IP4_IS_VALID_NETMASK() return correct value.
- Add DumpIpv4Address() in RedfishDebugLib and print IP address
when invalid IP or subnet mask address is detected.
