This patch implements IB_WR_REG_SIG_MR posted by the user.Baisically this WR involvs 3 WQEs in order to prepare and properly register the signature layout: 1. post UMR WR to register the sig_mr in one of two possible ways: * In case the user registered a single MR for data so the UMR data segment consists of: - single klm (data MR) passed by the user - BSF with signature attributes requested by the user. * In case the user registered 2 MRs, one for data and one for protection, the UMR consists of: - strided block format which includes data and protection MRs and their repetitive block format. - BSF with signature attributes requested by the user. 2. post SET_PSV in order to set the for the memory domain initial signature parameters passed by the user. 3. post SET_PSV in order to set the for the wire domain initial signature parameters passed by the user. This patch also introduces some helper functions to set the BSF correctly and determining the signature format selectors.
Has it already been explained somewhere what the abbreviations KLM, BSF and PSV stand for ?
