[ipxe-devel] [PATCH 0/3] [tg3] fixups for BCM5720

There are three problems with the tg3 driver on our Dell R820s using
BCM5720s:
1) Link is rarely detected
2) System crashes and reboots every time in tg3_transmit()
3) No frames of any type are ever received

The following patches "fix" these problems.  I tested them on said R820
(which stably works via PXE, getting large kernels/initrds over HTTP,
etc.) and an Optiplex 745 with BCM5745 (which suffered no regressions in
my tests).  Unfortunately, those are the only Broadcom cards we have.
