212 RX copybreak
219 This option controls the maximum packet length for which the RX
221 than RX copybreak bytes is received, it is copied into a new memory
222 buffer and the RX descriptor is returned to HW.
334 Dynamic RX Buffers (DRB)
337 Each RX descriptor in the RX ring is a single memory page (which is either 4KB
340 packets, the driver tries to reuse the remaining RX descriptor's space if more
347 1. Driver allocates page-sized RX buffer and passes it to hardware
349 |4KB RX Buffer |
355 HW as an RX buffer of size 4KB - 300Bytes = 3796 Bytes
357 |****|3796 Bytes RX Buffer|
361 RX packet is less than rx_copybreak bytes (in which case the packet is
362 copied out of the RX buffer into the linear part of a new skb allocated
363 for it and the RX buffer remains the same size, see `RX copybreak`_).
