ConnectX-4 Lx on FreeBSD 11.1 Simplified install

Starting with the latest document “Mellanox_FreeBSD_User_Manual_v3.0.0.pdf” i got stuck on missing symbol in bmake.

Searching found much has happened since 2015 - the publish date of above, e.g.

[base] Revision 291072 [base] Revision 291072

To summarize, current release FreeBSD 11.1 has built-in drivers for mlx5, however not loaded by default install. To install, do:

Append to /boot/loader.conf

hw.pci.honor_msi_blacklist=“0” # this is required on VMware



no MLX driver

pciconf -lcv | grep 15b3

→ none2@pci0:19:0:0: class=“0x020000” card=0x000315b3 chip=0x101615b3 rev=0x00 hdr=0x00

with mlx5 driver

pciconf -lcv | grep 15b3

→ mlx5_core0@pci0:11:0:0: class=“0x020000” card=0x000315b3 chip=0x101615b3 rev=0x00 hdr=0x00

ifconfig mce0

→ media: Ethernet autoselect <full-duplex,rxpause,txpause> (10GBase-CR1 <full-duplex,rxpause>)

status: active

Note: this is a FreeBSD guest on ESXi 6.5 with Virtual Ethernet using SR-IOV.

Perhaps the User Manual can be updated to reflect all the hard work that has been done in 2015 to get the driver into the official distro :-)

did you manage to compile with bmake and activate ISER on freebsd? That pdf document is old and not applicable for freebsd11-stable. What tool do I need to configure target on freebsd with ISER?
