[PATCH] libhns: Fix missing fields for SRQ WC
by Junxian Huang 27 Feb '25

27 Feb '25

From: Xinghai Cen <cenxinghai(a)h-partners.com> The sl and src_qpn fields in recv-WC are not filled when the QP is UD and has an SRQ. Here fix it. In addition, UD QP does not support RQ INLINE and CQE INLINE features. Reorder the related if-else statements to reduce the number of conditional checks in IO path.
