[U-Boot] [PATCH 04/14] net: gem: Remove WRAP bit from TX buffer description

[Michal Simek]

From: Michal Simek <mon...@monstr.eu>

Removing this bit causes that frame is sent only once.
(With wrap big one packet has been sent several times
which dramatically decrease throughput)

TRM: (Table 16-3: Tx Buffer Descriptor Entry)
