Bug #3082: network hangs

Hello,

I have installed Dragonfly 5.0 on a little computer having this network device :
re0 at pci0:4:0:0:	class=0x020000 card=0x816810ec chip=0x816810ec rev=0x02 hdr=0x00
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller'
    class      = network
    subclass   = ethernet

I've setup my network in the installer following what's prompted with a static IP address. I ended up with a re0 interface setup as such :
> ifconfig
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
	inet 192.168.0.100 netmask 0xffffff00 broadcast 192.168.0.255
	inet6 fe80::2e0:4cff:fe68:4e8%re0 prefixlen 64 scopeid 0x1 
	ether 00:e0:4c:68:04:e8
	media: Ethernet autoselect (1000baseT <full-duplex>)
	status: active

I can access my computer remotely and the computer can access remote computers without any issue. The network works fine in that meaning.

The problem begins to appear when there's more activity on the device than just a ssh connection (for example retrieving an iso with curl is enough).
After that the network hangs, sometimes I can get it back, sometimes I get a kernel panic. 
I can reproduce it everytime.

Anyway something seems wrong and makes the network unusable (I can't make src-create-shallow :/)

Tell me if you need files. I'm joining a screenshot from last kernel issue following a iso download (5.0rc2).

Regards,
