I'm a random software/network/hardware/systems guy who seems to be the WiFi and atheros driver maintainer.

I'm currently working on:

• Getting FreeBSD/mips installing and running well on various Atheros MIPS embedded platforms
• Working on FreeBSD Wifi support for 802.11n Atheros chips
• Hopefully shaping TDMA and 802.11s mesh into shape for 802.11n support
• bsdbox - a busybox style solution for FreeBSD embedded builds
• Working on NetworkRSS - network receive / transmit side scaling and CPU affinity

What I'd like to do for FreeBSD-12:

Scaling:

• NUMA aware malloc/KVA allocation
• NUMA aware vm page metadata layout
• NUMA aware driver / dmamem / dmatag layout
• Per-domain reserved memory/KVA, for large/huge allocations (eg 1G regions set aside for jumbo mbuf clusters, netmap style buffer allocation, third-party / commercial software, VMs, etc.)
• Multiple configurable AIO queue/pools (eg to limit AIO pools to different disk pools)

Environment:

• Graphical bootloader
• High resolution splash screen support for startup/shutdown
• VESA vt(4) support

Wifi:

• 802.11ac support
• QCA98xx 11ac chipsets support
• MT76xx 11ac chipset support
• TDMA 11n support, multiple TDMA stations
• RX rate / RSSI histogram
• move ath_rate_sample into net80211
• extend sample rate control to include aggregation length, TX power estimation, knowledge about queue depth and TID/WME parameters (eg knowing what queue a packet is going out on), etc.
• add airtime awareness to net80211
• add airtime scheduling to ath driver/sample rate control.

Embedded:

• make umtx hash size configurable, instead of 512 buckets
• look at why the loader cache wants 128mb ram and make it better autotune

Atheros stuff:

• background scan support without dropping frames
• squish ACK transmission during passive mode operation (before removing passive flag), DFS detection operation
• NAV bug workaround from ath9k
• ToA/ToD positioning information

Network:

• IPv6 UDP / RSS (from bz@)
• Teach the network stack about MIPS, etc that have alignment constraints (so it doesn't kernel panic)
• Split RSS platform/netinet support from RSS NIC support
• ethtool for FreeBSD (mostly define API and initial global options)
• NAPI style adaptive polling (for drivers using iflib)
• Import NETLINK or something like NETLINK

• EmbeddedDevices - A list of embedded devices supported by FreeBS
• UbiquityRouterstationPro - toying with FreeBSD 9 on the Ubiquity Routerstation Pro
• TpLink-Wr1043nd - throwing -HEAD onto the TP-Link WR1043nd.
