7 title: Peripheral-specific properties for a SPI bus.
10 Many SPI controllers need to add properties to peripheral devices. They could
11 be common properties like spi-max-frequency, spi-cpha, etc. or they could be
12 controller specific like delay in clock or data lines, etc. These properties
13 need to be defined in the peripheral node because they are per-peripheral and

37 A larger TX ring can improve pktgen's performance, while it can hurt
38 in the general case, 1) because the TX ring buffer might get larger

44 ring-buffers for various performance reasons, and packets stalling
45 the TX ring might just be waiting for cleanup.
