Kinetis EMAC: Make number of buffers configurable 16 RX buffers and 8 TX buffers is probably excessive. Nanostack version of driver successfully used 4+4, and data pump should be broadly equivalent. This means that switching K64F devices from Nanostack to EMAC increases base heap usage by 18K - observed in Nanostack border router builds. Add a config option to make it possible to lower the number of buffers. Defer consideration of lowering the default to later. 2018-06-06 10:13:19 +00:00			`{`
