Call b53_adjust_531x5_rgmii() and b53_adjust_5325_mii() from b53_phylink_mac_config() when we have a fixed PHY in preparation for removing b53_adjust_link(). Also move b53_adjust_63xx_rgmii() to b53_phylink_mac_config() where it logically belongs. Signed-off-by:

88E6250-family switches have the quirk that the EEPROM Running flag can get stuck at 1 when no EEPROM is connected, causing mv88e6xxx_g2_eeprom_wait() to time out. We still want to wait for the EEPROM however, to avoid interrupting a transfer and leaving the EEPROM in an invalid state. The condition to wait for recommended by the hardware spec is the EEInt flag, however this flag is cleared on read, so before the hardware reset, is may have been cleared already even though the EEPROM has been read successfully. For this reason, we revive the mv88e6xxx_g1_wait_eeprom_done() function that was removed in commit 6ccf50d4 ("net: dsa: mv88e6xxx: Avoid EEPROM timeout when EEPROM is absent") in a slightly refactored form, and introduce a new mv88e6xxx_g1_wait_eeprom_done_prereset() that additionally handles this case by triggering another EEPROM reload that can be waited on. On other switch models without this quirk, mv88e6xxx_g2_eeprom_wait() is kept, as it avoids the additional reload.

Instead of calling mv88e6xxx_g2_eeprom_wait() directly from mv88e6xxx_hardware_reset(), add configurable pre- and post-reset hard reset handlers. Initially, the handlers are set to mv88e6xxx_g2_eeprom_wait() for all families that have get/set_eeprom() to match the existing behavior. No functional change intended (except for additional error messages on failure). Fixes: 6ccf50d4 ("net: dsa: mv88e6xxx: Avoid EEPROM timeout when EEPROM is absent") Signed-off-by:

Philo Lu says: ==================== tcp: update TCPCB_EVER_RETRANS after trace_tcp_retransmit_skb() Move TCPCB_EVER_RETRANS updating after the trace_tcp_retransmit_skb() in __tcp_retransmit_skb(), and then we are aware of whether the skb has ever been retransmitted in this tracepoint. This can be used, e.g., to get retransmission efficiency by counting skbs w/ and w/o TCPCB_EVER_RETRANS (through bpf tracing programs). For this purpose, TCPCB_EVER_RETRANS is also needed to be exposed to bpf. Previously, the flags are defined as macros in struct tcp_skb_cb. I moved them out into a new enum, and then they can be accessed with vmlinux.h. We have discussed to achieve this with BPF_SOCK_OPS in [0], and using tracepoint is thought to be a better solution.

The BPF sample building code looks a little bit spaghetti-ish so move it out to its own Makefile snippet. Similar in the spirit to how we include lib.mk. libynl will soon get a similar snippet. There is a small change hiding in the move, the relative paths (../../.., ../.. etc) are replaced with variables from lib.mk such as top_srcdir and selfdir.

Daniel Machon says: ==================== net: sparx5: add support for port mirroring This series adds support for port mirroring, and port mirroring stats, through tc matchall action FLOW_ACTION_MIRRED. The hardware has three independent mirroring probes. Each probe can be configured with a separate set of filtering conditions that must be fulfilled before traffic is mirrored. A mirror probe can have up to 64 source ports and a single monitor port. The direction of a mirror probe determines if rx or tx traffic is mirrored from the source port to the monitor port.
