2023-12-27net: phy: nxp-c45-tja11xx: add MACsec statisticsRadu Pirea (NXP OSS)
Add MACsec statistics callbacks. The statistic registers must be set to 0 if the SC/SA is deleted to read relevant values next time when the SC/SA is used. Signed-off-by: Radu Pirea (NXP OSS) <radu-nicolae.pirea@oss.nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2023-12-27net: phy: nxp-c45-tja11xx: add MACsec supportRadu Pirea (NXP OSS)
Add MACsec support. The MACsec block has four TX SCs and four RX SCs. The driver supports up to four SecY. Each SecY with one TX SC and one RX SC. The RX SCs can have two keys, key A and key B, written in hardware and enabled at the same time. The TX SCs can have two keys written in hardware, but only one can be active at a given time. On TX, the SC is selected using the MAC source address. Due of this selection mechanism, each offloaded netdev must have a unique MAC address. On RX, the SC is selected by SCI(found in SecTAG or calculated using MAC SA), or using RX SC 0 as implicit.
