Subject: efi_loader: size fields in SimpleNetworkProtocol
X-Git-Tag: v2017.11-rc2~55^2~16
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=8db174d651e3f92ddb9660f1f8b8755b902c3c11;p=u-boot

efi_loader: size fields in SimpleNetworkProtocol

The size fields in the Simple Network Protocol are all
UINTN in the UEFI spec. So use size_t.

Provide a function description of the receive function.
