# 7ac2e6c3 25-Aug-2007 Kip Macy <kmacy@FreeBSD.org>

Fixes for 4 port and small packet optimization

- remove cpl->iff panic - we can't know the port number from the rspq on the 4-port
- pick the ifnet based on the interface in the CPL header
- switch to using qset 0 for egress on the 4-port for now - may change
when we start using RSS
- move ether_ifdetach to before the port lock gets deinitialized to avoid
hang in the case where there are BPF peers (cxgb_ioctl is called indirectly
when BPF peers are present)
- don't call t3_mac_reset if multiport is set, this was causing tx errors
by misconfiguring the MAC on the 4-port
- change V_TXPKT_INTF to use txpkt_intf as the interfaces are not contiguous
- free the mbuf immediately in the case where the payload is small enough to be copied
into the rspq
- only update the coalesce timer if for a queue if packets were taken off of it
- add in missed 20ms DELAY in initializaton vsc8211

- prompt MFC as this only applies to the 4-port which is currently completely
broken - OK'd by kensmith

- switch adapter and port lock over to using sx so that resources
can be allocated atomically
- add debug macros for printing lock initialization / teardown
- add buffers to port_info and adapter to allow each lock to have a
unique name
- destroy mutexes initialized by cxgb_offload_init
- remove recursive calls to ADAPTER_LOCK
- move callout_drain calls so that they don't occur with the lock held
- ensure that only as many qsets as are needed are initialized and
destroyed

# 10faa568 29-May-2007 Kip Macy <kmacy@FreeBSD.org>

When building cxgb as a module make include paths relative to the driver's root.
This will make it possible to build the module out of tree against an older src tree.

- upgrade to reflect state of 1.0.0.86
- move from firmware rev 3.2 to 4.0.0
- import driver bits for offload functionality
- remove binary distribution clause from top level files as it
runs counter to the intent of purely supporting the hardware

Make DMA tags per-queue to facilate parallel mappings
Defer mbuf allocation and initialization until after data has already been
received in a cluster

This reduces cpu utilization somewhat, but it only improves the rx path.
Recent changes to TCP appear to make us rate limited by the TX path.

This is the first step in reducing mbuf management overhead for manipulating
clusters.

Increase response queue size to avoid starvation, add a counter
to track it when it does occur.


# 97ae3bc3 31-Mar-2010 Navdeep Parhar <np@FreeBSD.org>

Multiple fixes related to queue set sizing and resources:

- Only the tunnelq (TXQ_ETH) requires a buf_ring, an ifq, and the watchdog/timer
callouts. Do not allocate these for the other tx queues.

Multiple fixes related to queue set sizing and resources:

- Only the tunnelq (TXQ_ETH) requires a buf_ring, an ifq, and the watchdog/timer
callouts. Do not allocate these for the other tx queues.

- Use 16k jumbo clusters only on offload capable cards by default.

- Do not allocate a full tx ring for the offload queue if the card is not
offload capable.

- Slightly better freelist size calculation.

- Fix nmbjumbo4 typo, remove unneeded global variables.

Fix for a cxgb(4) panic. cxgb_ioctl can be called by the IP and IPv6
layers with non-sleepable locks held. Don't (potentially) sleep in
those situations.
