[PATCH 02/17] RDMA/core: Save the MR type in the ib_mr structure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a preparation for the signature verbs API change. This change is
needed since the MR type will define, in the upcoming patches, the need
for allocating internal resources in LLD for signature handover related
operations. It will also help to make sure that signature related
functions are called with an appropriate MR type and fail otherwise.
