fix: Correct bit mask for GetBMCServiceStatus cmd

Bit 14 and 15 of GetBMCServiceStatus command response represents
status of Video and USB redirection. These 2 bits should match since
a single service maintains both. The logic for the same is already
implemented. But incorrect mask resulted in error values when previously
un-used bits(bit 13) got defined for new services.

This change corrects the bit mask to extract only bit 15

Tested:
Verified commands is giving expected response
Command:  ipmitool raw 0x30 0xb2
Response: 68 e0
Command:  ipmitool raw 0x30 0xB1 0x00 0x68 0xe0
Response: Success
Command: ipmitool raw 0x30 0xb2
Response: 00 00

Intel IPMI OEM support library

This component is intended to provide Intel-specific IPMI[3] command handlers for OpenBMC. These handlers are intended to integrate BMC with servers based on Intel architecture.

Overview

intel-ipmi-oem serves as an extension[1] to OpenBMC IPMI daemon[2]. It is compiled as a shared library and intended to both:

  • override existing implementation of standard IPMI commands to comply with Intel-specific solutions,
  • provide implementation for non-standard OEM extensions.

Capabilities

Related features provided by the library are grouped in separate source files. Main extensions to vanilla OpenBMC IPMI stack are the following:

  • Acquiring SMBIOS data over IPMI
  • Commands for better integration with Intel hardware
  • Firmware update extensions
  • Extended parsing of IPMI Platform Events[4]
