PATCH 1/1 rdma: Update device capabilities flags
From: Leon Romanovsky <[email protected]>
In kernel commit e1d2e8873369 ("IB/core: Add PCI write end padding flags for WQ and QP"), we introduced new device capability to advertise PCI write end padding.
PCI write end padding is the device's ability to pad the ending of incoming packets (scatter) to full cache line such that the last upstream write generated by an incoming packet will be a full cache line.
This commit updates RDMAtool to present this field.
