We eliminate data_key_valid boolean and replace it with indicators container to indicate: - Is the descriptor protected (registered via signature MR) - Is the data_mr key valid (can spare LOCAL_INV WR) - Is the prot_mr key valid (can spare LOCAL_INV WR) - Is the sig_mr key valid (can spare LOCAL_INV WR) Upon connection establishment check if network portal is T10-PI enabled and allocate T10-PI resources if necessary, allocate signature enabled memory regions and mark connection queue-pair as signature enabled. (Fix context change for v3.14-rc6 code - nab) Signed-off-by: Sagi Grimberg Signed-off-by: Nicholas Bellinger --- Reading git-diff-tree failed
