 Ok, the plot thickens.
 Some months ago I switched to using an igc0 instead:
 igc0 at pci6 dev 0 function 0, 64-bit DMA: Intel(R) Ethernet Controller I225-LM (rev. 0x03)
 igc0: txrx interrupting at msix1 vec 0
 igc0: txrx interrupting at msix1 vec 1
 igc0: txrx interrupting at msix1 vec 2
 igc0: txrx interrupting at msix1 vec 3
 igc0: link interrupting at msix1 vec 4
 igc0: PHY: OUI 0x984fee model 0x0000, rev. 0, PHY FW version 0x8754
 igc0: NVM image version 1.57, EtrackID 80000180
 igc0: Ethernet address ...
 
 today the machine stopped being accessible from the network, and in the log I saw
 
 Oct  7 23:03:39 exadelic dhcpcd[2783]: ps_root_recvmsg: No buffer space available
 
 which looks like the symptoms I saw with rge0.
 
 Could there be a common underlying cause in the network code?
