Subject: [PATCH] hw/net/lan9118: Signal TSFL_INT flag when TX FIFO reaches
specified level mainline inclusion commit
895a803ce91704f28c9b49621a4f589273289f1e category: bugfix
---------------------------------------------------------------
The LAN9118 allows the guest to specify a level for both the TX and
RX FIFOs at which an interrupt will be generated. We implement the
RSFL_INT interrupt for the RX FIFO but are missing the handling of
the equivalent TSFL_INT for the TX FIFO. Add the missing test to set
the interrupt if the TX FIFO has exceeded the guest-specified level.
This flag is required for Micrium lan911x ethernet driver to work.
