From: wenglianfa <wenglianfa@huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB71IG ---------------------------------------------------------------------- According to the IB protocol, the qp_num of the GSI QP must be set to 1. Therefore, the QP must be created in BANK 1. Currently, only QPs in BANK 0 and 6 can use extended SGEs, but the GSI QP in bank 1 also need to use extended SGEs. To fix it, the restriction is changed to allow QPs in BANK 1 and BANK 6 to use extended SGEs.
