The designware driver has a bug in setting the tx length into the dma descriptor: it always or's the length into the descriptor without zeroing out the length mask before.
This results in occasional packets being transmitted with a length greater than they should be (trailer). Due to the nature of Ethernet allowing such a trailer, most packets seem to be parsed fine by remote hosts, which is probably why this hasn't been noticed.
Fix this by correctly clearing the size mask before setting the new length.
Tested on socfpga gen5.
