Subject: net: nfs: Use consistent names for the rpc_pkt
X-Git-Url: http://git.ipfire.org/?p=people%2Fms%2Fu-boot.git;a=commitdiff_plain;h=0517cc45e502cd7858beb37b8fab754a2fa52830

net: nfs: Use consistent names for the rpc_pkt

Use the same name throughout the nfs code and use the same member of the
union to avoid casts.
