In a real RoCE v2 network it is possible to have two Sections of network have same IP hence same gid. However those may have different vlans. During connection resolution it is important to report the actual vlan on which the MAD packet was received instead of relying on other means to resolve vlan-id. ib_find_gid_index should not be used to resolve the vlan-id using sgid of the local system where the packet was received. Our device has the capability to report the actual VLAN-ID in the GSI qp completions. Since we have the capability our driver should move away from resolving the vlan-id with the help of SGID at the destination port.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
