# c912f19e	21-May-2021	Marc Kleine-Budde <mkl@pengutronix.de>	can: mcp251xfd: introduce struct mcp251xfd_tx_ring::nr and ::fifo_nr and make use of it This patch removes the hard coded assumption that the TX ring uses hardware FIFO 1. This allows the hardware F can: mcp251xfd: introduce struct mcp251xfd_tx_ring::nr and ::fifo_nr and make use of it This patch removes the hard coded assumption that the TX ring uses hardware FIFO 1. This allows the hardware FIFO 1 to be used for RX and the next free FIFO for TX. This gives the opportunity to minimize the number of SPI transfers in the IRQ handler. The read of the IRQ status register and RX FIFO status registers can be combined into single SPI transfer. If the RX ring uses FIFO 1, the overall length of the transfer is smaller than in the original layout, where the RX FIFO comes after the TX FIFO.
