Architecture: x86_64
Machine: amd64
When using ral on NetBSD-current with the following hardware:
ral has not been converted to device_t
ral0 at pci2 dev 2 function 0: Ralink Technologies RT2561S 802.11b/g (rev. 0x00)
ral0: interrupting at ioapic1 pin 17
ral0: 802.11 address 00:1f:1f:59:57:52
ral0: MAC/BBP RT2561C, RF RT2527
ral0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ral0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps

and wpa_supplicant on a wpa2 network, setting up the network connection works fine,
but after a short time using rtorrent with a few torrents, the network connection
is lost.
When I then ping, I see:
ping: sendto: No buffer space available                                                                                                                                                                             

Same load & setup works fine with a wired network card, e.g.
re0 at pci7 dev 0 function 0: RealTek 8168/8111 PCIe Gigabit Ethernet (rev. 0x02)
re0: interrupting at ioapic0 pin 17
re0: Ethernet address 14:da:e9:20:0b:ce
re0: using 256 tx descriptors
rgephy0 at re0 phy 7: RTL8169S/8110S/8211 1000BASE-T media interface, rev. 2

Confiure ral0 as above on a WPA2 network, produce load, wait a few minutes.
