Broadcom BCM5719 pci-e supported?

Found the network card for sale ( HP NC331T) will it work fine with Openwrt?
Thank you!

In general, if it's a LAN NIC and it has official (in-tree) Linux kernel drivers, it should work on OpenWrt as well. Stable is on a bit of an older kernel (4.14 at the moment) but master is moving to 5.4 e.g..

A quick internet search should give you some clarity, from what I can find it looks supported.
