From 524381ef281bb886f215ac9341b3c2e5b59ec178 Mon Sep 17 00:00:00 2001 From: Yonatan Nachum Date: Wed, 22 Jul 2026 11:33:31 +0000 Subject: RDMA/efa: Expose 64-bit send WR ID support to userspace Currently EFA WRs support 16-bit request ID, this requires EFA to manage a translation table to translate the IB WR ID from 64-bits to 16-bits and translating it back on CQ completion. Expose a new device capability to handle 64-bit request ID for SQ WRs allowing userspace to directly post the 64-bit ID to the device.
