[PATCH 1/2] if_tsec: Fix MII communication

Use a common tsec_mii_wait() function to busy wait for status changes. The status indicators are not set immediatly after a command. Discard the first value. Unlock the PHY mutex after a timeout in tsec_init_locked(). Tested on the P1020RDB. --- sys/dev/tsec/if_tsec.c | 58 +

[PATCH] if_tsec: Defrag only on demand

Defragment the transmit mbuf chain only if necessary. Use a method similar to the if_dwc driver. Use a wmb() before the flags of the first transmit buffer of a frame are written. Group transmit/receive structure members for better cache efficiency. Tested on P1020RDB. TCP transmit throughput i

[PATCH 1/2] if_tsec: Fix input statistic counters

[PATCH 2/2] if_tsec: Fix deadlock

The tsec_error_intr_locked() is called with the global lock owned (e.g. the transmit and the receive lock are both owned). We must not call tsec_receive_intr_locked() while owning the transmit lock. The normal receive interrupt takes care that frames are received, this is none of the business of

TCP_NOTSENT_LOWAT on FreeBSD?

Hello, I use the mDNSResponder from Apple in embedded devices on top of the FreeBSD network stack. I tried to update from v878.270.2 to v1096.40.7: https://opensource.apple.com/tarballs/mDNSResponder/ However, the Linux/macOS specific feature TCP_NOTSENT_LOWAT is now used in the new version:
