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.

Most of the proposed objects are working in the scope "dev"
and will implement the same logic. Move the code to utils.c,
so other objects will be able to reuse the code.
